I really struggled on this one. Reading is usually effortless, but this book required concentration and rereading of passages. I didn’t find it interesting, and it really didn’t hold my attention, which was disappointing as I thought blurb sounded so good. I forced myself to keep reading just because I hate not knowing how a book ends, but I kept having to put it down for lack of motivation, and ended up skim-reading the majority of the book.There are some intriguing ideas here - notably the special plant-based serums and how they interact with the strange biology of the human/vampire hybrids but it wasn't enough to make this book good
