Claiming Moon — B.J. McCall

Werewolves, dragons and werecats have gone missing. Working undercover, Jackson Graham of the Paranormal Crime Unit has infiltrated a group trafficking in shifters and he's on the brink of taking down the criminal network. During a short respite in the case, he visits his pack and runs into Grace. He's been secretly in love with Grace for years, but this she-wolf is destined to mate with his cousin, York.

But Grace has other plans. She's refused to run beneath the Claiming Moon with York, and Jackson is the wolf she wants.

They share one night of passion, but must part ways. Jackson is in the middle of an undercover operation and Grace, an investigative reporter for an online paper, is intent on solving the mystery of the missing shifters.

When Jackson and Grace's paths cross again, he's the buyer and she's the contraband.
