Wolf Claim by Emma Dean

Noah is the levelheaded twin who has always looked out for Liam, not that many people could tell the difference between the two of them. Their coping mechanisms for the last decade of hell was to make jokes and laugh it all off. It has its upsides and downsides, which includes no one in the pack really taking them seriously. When their new witch offered to scry for his mate, he agreed, ready to settle down, but the last thing he expected was to find out that his mate was a raven shifter – notorious assassins within the paranormal world. How is he supposed to get in contact with her when no one really knows anything about them? Noah is resigned to his lonely future, and then their blood debt to a raven flock gets called in – to free his mate from the pack that has captured her.
