The author does a good job of building suspense and writing action-packed, high-tension events that kept me reading one book from cover to cover. The plot is nice that it offers more than just pure romance--there are other interesting characters and an overall crime/mystery goal of the characters where I definitely felt that this book at times became more than being a "boys love" series of novels and was rather a detective/action series where the main characters happened to be gay.
That being said, the story is far from perfect. Conversations tended to drag during very dramatic moments, and it took a /very/ long time for Yuuto to grow a pair. I mean, with the first novel being in a prison setting and all, I was surprised Yuuto didn't die like the 2nd day or something. I found it really hard to like him for so much of the first book because he was so whiny and all talk but no action. Like, he really acted tough and made enemies all over but he couldn't defend himself worth **! That really annoyed me because as cool looking as the talented Takashina Yuu made Yuuto, for so much of it he really fell into the stereotypical weak-and-girly-"uke" of many BL series.
Situations also tended to be highly romanticized and over dramatized. Minor characters tended to remain flat without much growth. Some conversations and quips were witty and fun, but some dialogues could sound forced and boring.
Overall, I felt compelled to read it and keep reading it, but I'm not in a hurry to reread it ever again. I'd recommend this if you were perhaps bored on a plane, but I am sure you can find better novels than this. If you don't mind a little cheese or perhaps enjoy a little drama/romance and you just love having the hot illustrations, then I think you'd enjoy reading this more than I did.
