Killer Smile by Tawna Fenske

He’s a covert operator. A killer built by the U.S. Army. He’s tasked with taking out his dream girl—and not on a date.

Targeting Nicole should be simple, since she hates his guts. Sebastian The Dentist—yes, a real freakin’ dentist, don’t make it scary—has wanted Nic since they first locked horns. He’s not sure why they’re enemies, but he knows there’s more to the sweet daycare owner than crayons and cardigans. But discovering her secrets lands them both in danger they’ll dodge only by working together.
Between awkward wedding dates and puppies with no personal space, Sebastian and Nic get closer. They’re also close to discovering if Nic’s dead associate may not be so dead.
If Sebastian can stop her from hating him long enough to eliminate the threat, they might just fall in love. But only Nic can stop him from hating himself.
