My Sister is a Werewolf initially appears to be one of the slightly humorous paranormals that are so popular at the moment. While this book doesn't have any particular humor, it does have a very well-written tale of two people with lots of baggage falling in love and carving out a future together. It's a follow-up to three other books about the heroine's brothers, but this book works fine as a standalone novel and any relevant backstory is given.
Elizabeth Young isn't quite what she seems - a research scientist living in a quiet backwater. Yes, she is those things, but she also has a secret life as a Werewolf, and her research aims to “cure” herself of lycanthropy. She has broken away from her pack to live on her own, but she has a “mate”, Brody, so her life is not her own, even though she has run away from him.
Jensen Adler is the local veterinarian and little else. Since his fiancée, Katie, died he hasn't dated any other women and isn't really living much of a life, just looking after his grandfather and working. When some friends arrange a blind date for him, he finds himself completely knocked sideways by a woman - unfortunately not his date. The woman seems to respond to him, and they end up leaving the bar together.
The relationship in this book is rather backwards - sex first, getting to know each other later - but there's a reason for it which becomes clear in due course. Jensen finds himself with a woman wavers between trying to seduce him or to run away. Her behavior appears in some ways outrageous, but he is also aware that this isn't her normal nature. Jensen notes there are some strange things about Elizabeth - her brothers are also a bit odd - yet he continues to try to have a relationship with her, to put up with her vacillations about whether they should see each other.
Most of this book focuses on the relationship between Jensen and Elizabeth. The couple appear on almost every page, and even the return of Brody and the potential harm he could cause Jensen doesn't intrude too much into the plot. This story is about characters getting to knew each other and finding out each others' history, even though much has to be kept in the dark.
Kathy Love’s writing style here makes this an easy read with excellent pacing. Despite the fact that the plot is actually rather thin, it feels like a satisfying book to read and is never boring. The author could have made more of the threat from Brody, especially as the final denouement happens very quickly and is solved in a rather facile way, but it is still a worthwhile read.
