1 1/2 stars.
Romantic suspense my ass. This book is about 20% mystery, 50% romance, and 30% family stuff. There's way too many conversations about Gavin's family, and Ellery and Gavin fall in love way too easily for people who have very few conversations about themselves. Ellery is the classic damsel in distress--having been struck on the head, she has temporary amnesia, and Gavin is the doctor who rescues her from the ocean and treats her. She's beautiful and vulnerable, and that's apparently the only thing Gavin needs to be smitten.
A bunch of cousins help him out, and they're pretty much all interchangeable and not necessarily great characters. Everyone assumes Gavin is dating Ellery, this girl literally no one knows, and apparently they think that because he wants to help her...? He's a doctor, shouldn't he generally want to help people? There's a saucy reverend, some sly old ladies (a must in Southern novels), ridiculous over the top rednecks (another requirement, unfortunately), shady rich people, magnanimous rich people, and some insta-love/lust-mistaken-as-love.
It's easy to read, I'll give it that, but it's also so plot light I honestly wonder who the hell put it as romantic suspense. There's very little mystery. We knows Ellery didn't do it. By the time Ellery remembers enough, we pretty much know all the suspects (who we basically don't see until the end) and there's no actual suspense because the book doesn't contain any real stakes. We learn fairly early police corruption is suspected, and that's pretty much the only thing that we need to piece the general rest together.
