Multiples Mystery (Harlequin Intrigue Series #1124) Book

Olivia Capri knew giving birth to quads would cause a stir in her media-starved small town. But she didn't realize it would bring back Zac Bishop, the boy she'd once loved with all her teenaged heart. Luckily, as sheriff, he'd returned just in time. It seemed someone was after her and her babies thanks to a past she knew nothing about. And though she knew whoever it was didn't stand a chance against Zac and his protective nature, reminiscing about old times stirred up too many long-buried emotions. Still, Zac assured her everything would be okay, all she had to do was trust him. And she did. With everything but her heart.
