Agent Cooper Dayton never thought anything could be harder than solving murders. Until he had to plan a wedding.

After taking down an old adversary, Agent Cooper Dayton of the Bureau of Special Investigations has earned a break. Not that planning a wedding to his sexy shifter partner, Oliver Park, is necessarily stress free, but it's better than worrying about the ominous warning, delivered months ago, that Cooper's life is in danger.

When he's dragged to an event by his family, Cooper braces for an awkward evening, but instead finds himself in the middle of an ugly feud between Park's ex and a rebel pack leader. What was supposed to be a quick outing turns into a full-blown murder investigation after the pack leader ends up dead, Park's ex goes missing, and Cooper and Park are sent a series of disturbing wedding gifts that are somehow connected to it all.

The list of potential suspects is long, and with the bodies piling up, Cooper must turn to the one person he trusts the least: the villain he's already put behind bars once and who has nothing to lose by lying and everything to gain if Cooper is out of the picture—for good.

Contains mature themes.
