Cattail Ridge — T.L. Haddix

Book Four in the Firefly Hollow series. 

After a cutting betrayal by the father of her child, Emma Campbell swore off men. Convinced she'd never find the kind of love her parents had, Emma devoted her life to raising her daughter and building her business. Surrounded by a close-knit family who loved her, she ignored her loneliness. Until the day family friend Archer Gibson kissed her. 

Archer had been in love with Emma since the first day he'd laid eyes on her five years ago. He'd never acted on that love, not feeling worthy of Emma's attention, but now that he'd made some changes in his life, he was ready to go after what he wanted most--a place in her life and in her heart. His biggest obstacle? Convincing Emma they both deserved a chance at happiness.
