Overall, this book was okay. The author's writing style and characters pulled the reader into the story. The plot switched back and forth between a brother and a sister after being separated, so there was good character development for the brother. The sister's character development could have used a little bit of work. Several situations happened that caused her to have PTSD, but it was barely hinted at. Her friendships could have been delevoped more in comparison to the brother's as well.
The sex scenes in the book felt like an old man was writing smut for other old men. They also felt out of place most of the time. The sex scenes felt very much the action of sex and not emotional. Though the one or two more emotional ones had a weird brother sister vibe.
