I've been a Mia Sheridan fan since the days of Archer's Voice. And while I enjoyed her voice in this story, as I always do, this particular story didn't draw me in like I'd expected it to.

However, I plan to give this one another shot very soon!

3 ⭐️

“Heart of the Sun” offers a unique blend of dystopian survival and second-chance romance, with an intriguing premise that kept me curious. While the pacing was uneven and the romance slow to develop, Emily and Tuck’s dynamic had potential, especially as the stakes rose. The world-building and action could’ve used more depth, and some plot elements felt undercooked, but overall, it’s a decent read for fans of slow-burn stories with apocalyptic vibes. Thanks to Harlequin Trade Publishing and Harlequin Audio for the advance copy!

I thought this was very good and I will have to add this to the shop shelves. Thank you for the chance for us to review.

I really enjoyed this book!! This was more of a Romantic Suspence which was nice change of pace!!! 4 stars!!

love love love Mia!
never met a book of hers i did not love. This one was no exception! Her writing is always flawless and effortless! Can't wait to see what she has for us next!

A Heartfelt Journey of Healing and Hope!

Mia Sheridan has once again crafted a story that is as emotional as it is beautiful. Heart of the Sun pulled me in from the very first page and never let go. The characters are raw, vulnerable, and achingly real—each carrying wounds that make their journey toward love and redemption all the more powerful.

What I loved most is how Sheridan balances heartbreak with hope. She doesn’t shy away from pain, but instead shows how resilience and love can light even the darkest corners. The romance unfolds with tenderness and authenticity, making every moment between the characters feel earned and deeply moving.

This book is not just about falling in love—it’s about healing, forgiveness, and finding the courage to embrace happiness after hardship. By the time I reached the final pages, I felt both shattered and whole, which is the magic Mia Sheridan always delivers.

If you’re looking for an emotional, beautifully written romance that stays with you long after the last page, Heart of the Sun is a must-read.

⭐⭐⭐⭐⭐

A second chance romance. Former friends turned enemies come back together under circumstances that no one could have predicted. Will they get through this together or will they continue hate to each other?

Loved this book so much!!!!! I love anything Mia writes. This was definitely in the top 5 of what I have read from her. I can’t wait to see what’s next

This was my first Mia book and I am not sure how to feel about it. This story unfortunately did not hold my attention and I was actually kind of bored reading & listening to the audiobook. I ended up DNF’ing it only a couple chapters in.

Others may really enjoy this book but it unfortunately was not for me.

Thank you so much, NetGalley, Harlequin Trade Publishing | Canary Street Press and The Hive for the gifted copy!

Heart of the Sun by Mia Sheridan

Childhood friends Tuck and Emily are reunited years later when she hires him as her bodyguard, just as a massive solar flare plunges the world into chaos. Amid the darkness and upheaval, they must navigate survival, their past, and the heat still lingering between them.

My thoughts: This was a quick read and kept my attention easily! I didn’t realize it would turn post-apocalyptic, so that was definitely a surprise, and it kept me invested. I liked the POV switches, which gave more insight into both Tuck and Emily, but the romance itself didn’t feel as intense as I expected - I wanted a little more chemistry to really spark.

Thank you to Harlequin Trade Publishing | Canary Street Press and NetGalley for the eArc version of Heart of the Sun.

I loved every second of this dystopian/slow burn/bodyguard romance. With a sweet beginning, Emily and Tuck were childhood best friends whose lives were torn apart suddenly. Tuck reappears in Emily’s life, where she is a celebrity, and things start to heat up until a major solar flare takes down the power grid. The two experience some harrowing times after that, and I can say their chemistry paired with the unknown that inherently comes with an apocalyptic event had me on my toes!

You will definitely want to read this one from Mia Sheridan. Heart of the Sun will capture your heart with its sweetness, slow-burn intensity, enemies-to-lovers vibes, and dystopian thrill. Five stars!

Thank you to NetGalley and Mia Sheridan for the eARC of Heart of the Sun. I have read other Mia Sheridan book and love her writing. This book started slowly in the beginning but eventually had my attention and I found myself wanting to know what happens to the characters. However, I felt like the book had a hard time keeping my attention throughout the book about halfway through. I felt as though Charlie was a useless filler character and Tuck was just self-loathing and never connected with anyone until the very end. Overall, I enjoyed the book but I felt there should have been more connection between Tuck and Emily sooner in the book rather then right at the end.

Mia Sheridan can do no wrong and this book was really good! From the way she writes romance to the way you swoon but also hold your breath because of the dystopian-like elements she added in this one, I really enjoyed it and can't wait for more books from her!!

Heart of the Sun by Mia Sheridan
3.8 Stars rounding to 4 on here.

Thank you Harlequin Trade Publishing| Canary Stress Press for the eARC through Netgalley. I am so glad I got the opportunity to read this in exchange for a review.

Okay first of all.... wow. Secondly, this is definitely not what I normally read when it comes to romance books but I really have a fun time with this one.
This is also different to other Mia books I have read too but I still enjoyed reading it.
This book kept me very intrigued and invested in how it was going to go even though it was very slow start for me but then it picked up which had me locked in completely.

Emily and Tuck were childhood friends, they haven't seen each other in a decade especially since Tuck was in jail. Emily turns into popstar, and when Tuck gets out of jail and visits her mom she suggests him working security for her. He does and then a lot of things go downhill from there and its a whole journey of survival for all people involved.
It was a trip reading this and I genuinely wouldn't know what to do if I was in the situation that they were in after a plane crash.

I would recommend this book for those that want a little twist in their romance books for sure because this was a journey and I was so intrigued once the story picked up.

Thank you again to the publishing company for approving me for an eARC for this read. I am happy I got the chance to read and review.

I absolutely love Mia’s writing I can always depend on her for a good escape! Something about her stories always captivate me!

This was such a interesting dystopian romance that really made think about how I would handle the challenges Tuck and Emily encountered as they fought to survive their unique circumstances. I enjoyed Tuck's ability to adapt and thrive, and Emily's growth as she learned from Tuck's example. It's horrifying to realize that something like this could actually happen and that adds another layer to the drama. The audiobook was a great way to consume this novel and the narration very well done.

There were moments when I was stressed out, and others when my heart wouldn’t stop pounding. The burn was burnnnnning

Was definitely excited to read this one. I love Mia Sheridan books so I was excited to try out this one as my first novel. The cover is lovey and the description looked so fascinating! I was obviously hooked! However, I found myself DNF-ING this one. I think it was just a little too slow. I started skipping pages until eventually I stopped reading all together.. I do like the premise of the plot so I may return to this book as an audiobook later on! Thank you for the arc!

dnf

the premise was interesting but once i started reading i couldn’t do it. it felt the romance was more of a sub plot. the main characters were annoying and were too much for me.

I really enjoyed this book, but I have to be honest—it just wasn’t my favorite. It was good, don’t get me wrong, just not totally my vibe this time. That said, I know this story will absolutely hit the mark for a lot of other readers.
Mia Sheridan’s writing is always beautiful, and I’ll definitely keep picking up anything she puts out. This one just didn’t land quite the same for me—and that’s okay
