The Artemis (McKinley Brothers #5)
Alexis Ashlie

But we’re both adults here, and it probably wouldn’t be so bad if we indulge our fascination with each other just a little bit. After all, who can resist the sexy charms of a toned, rugged, ex-officer of the Canadian Armed Forces, with his arresting hint of Native American blood, glinting black eyes, and thick, long . . . ponytail?
Then some creep starts sending me flowers: living ones, and then dead ones. Sinister, scary . . . dangerous. It feels good to have this big, strong man by my side. But even as he fights to save my life, will he also shatter my heart?
