I've been frustrated with the other book I'm reading, so when this popped up on Netgalley I pounced immediately, and proceeded to read the whole thing in a single day. I have a really hard time pinning down what it is about Lisa Kleypas that makes her books so engrossing, because honestly I don't love the tropes. This one in particular is very "innocent young women enchants hardened man of the world" which is Not My Fave... but I devoured Marrying Winterbourne and Devil in Winter too, so it just goes to show Kleypas can sell me on it. There are some new elements here, specifically Cassandra being pressured halfway into an eating disorder by her chaperone (it is not at all clear what's going on there, since she's also consistently described as one of the most beautiful women in London and I'm pretty sure our current fad for thinness is more recent) and the portrayal of Severin as possibly implied autistic -- unable to read social situations, has a hard time processing his own emotions, some kind of sensory processing -- but only when convenient for the plot. I don't feel equipped to evaluate either of those elements, but I definitely flagged them. There's a very charming subplot about a kid Severin takes in, and all the familiar faces from the other Ravenels books make appearances. The overall plot is kind of thin but if you want escapism about a guy with tons of money throwing that money at a lady's problems to make them go away (and in this day and age, I *frequently* want that escapism), Kleypas is your girl!
