Jack's Claus (The Keepers #4)
Jess Buffett

Nick is used to bringing joy to others, he is Santa Claus after all, but where his mate is concerned, he just can’t seem to get it right. When Jack becomes the sole target for their enemy, Nick will stop at nothing to keep his mate safe and prove once and for all they are meant to be.
With the story coming to an end, the Keepers will discover not only who they truly are, but what they are capable of...and just perhaps, what the future holds.
