The Trouble with Nerds - The Morrison Family, #11

Clean contemporary romance with suspense elements. Odd things keep happening to Dr. Sara Newton. She's a soon-to-be-unemployed pediatrician with an alleged stalker, a hot cop on her heels breathing dire warnings, and way too much student debt. It doesn't help that the hot cop is Clay Morrison, her best friend's older brother. The man has made her heart pound and her palms sweaty since puberty. The trouble is, he only interacts with her when he's expounding on new security measures.
He sees threats everywhere. Clay Morrison is frustrated. He hates his new job, misses his Army Ranger days, loves his well-meaning, pushy family-and when did sweet Sara Newton grow up? She won't admit she has a stalker, and she won't keep out of his thoughts. He can only protect someone in denial for so long. No matter how attractive she is... Clay and Sara are circling each other, trying to meet in the middle.
Then a brand new threat sends them in a completely different direction.
