The Brood by Devney Perry

A small town, forced proximity, age gap romance from bestselling author, Devney Perry.

The last thing Wilder Abbott needs is a houseguest. Solitude has been his stoic companion for nearly a decade. He prefers to brood over his mistakes in seclusion. Besides, he gets enough social interaction as a high school science teacher in Calamity, Montana.
But when his oldest friend calls, begging for a favor, Wilder begrudgingly agrees. For the next two months, he’ll give up his guest room to his friend’s little sister.
Iris Monroe isn’t the girl Wilder remembers. Gone is the shy, quiet mouse ten years his junior who always had her nose in a book. Grown-up Iris talks too much and asks too many questions, especially about his past. And her bright smile and clear blue eyes are hard to ignore.

Two months. He just has to survive two months. Except Iris is as nosy as she is beautiful. And his secrets prove hard to hide when she’s living under his roof.
