This was a good Military Space opera, although a bit repetitive in places.
A good ending to the series although left open for more.

A fantastic end to the story arc. The Commonwealth and Theocracy have a showdown, who will win, and will the price be too high. Well-written story with people you care about. You definitely need to read the previous books in the series, but they are just as exciting to read as this one. Looking forward to the next book by this author.
I received this free from NetGalley and the publisher for an honest review.

The latest in The Angel in the Whirlwind series is well up to the standard of the earlier novels. Devotees of the series will be pleased that there are to be further novels set in the same universe.

Tense action and dangerous outcomes!

Despite some Commonwealth opposition, the final showdown with the Theocracy is given full approval after the true madness of that Empire's reactions to loss are revealed. The harsh reality is exposed when the Theocracy explodes seeded nuclear devices on an occupied planet just as the Commonwealth is set to liberate it, ensuring the planet and its inhabitants to total destruction. Kat is left handling a humanitarian crisis on one hand and the political ramifications on the other.
Operation Hammer is devised. Kat Falconer as a Commodore of the fleet and second-in-charge will have to call on all the cunning, stealth, and giftedness she has in the final showdown. The Commonwealth takes the fight to the very centre of the Theocracy's domain--to their home planet Ahura Mazda. The battle will be hard fought. Lives will be lost and treachery is a heartbeat away. The true madness of the fanatical leaders actions will continue to be exposed.
Kat is facing some of the hardest moments of her life, both on the personal and professional front.
The resolution left me with similar feelings I had at certain times in the Honor Harrington series. I found myself hanging on the edge of remorse and frustration, and relief that there would be more to come.
Another grand and surprising finish to Kat's ongoing challenges.

A NetGalley ARC
(May 2017)

Once again Kat Falcone helps save the day but not without a very big cost. The Theocracy has shown that they will not hesitate to devastate an entire planet rather than give it up. Operation Hammer is an assault on Ahura Mazd, the home planet of the Theocracy. This massive operation is seen as the only way to both stop and win the war. Kat pays a massive personal price for the victory while at home an equally massive strike hits her family. This is space opera on a grand scale. Start at the beginning to follow Kat as she fights battle after battle. While this is the last book in the Angel in the Whirlwind arc Kat will be back in another series soon.
