Thanks for adding Betrayal to your "maybe will read" library. I hate to self-promote, but I do genuinely hope you check it out because the Red Wine, Romance, and Revenge series is one I poured my heart and soul into. If you're looking for a werewolf book that isn't just werewolf-y — without the cliches and more gore, drama, femme fatale badasses, and women who can hold their own — Betrayal is your cup of tea and it does not spoil Chains whatsoever. (Chains is the first book, currently being rewritten).
And that's my testimony. Do with it what you will. :)
