Red Lily - Nora Roberts

Hayley Phillips came to Memphis hoping for a new start, for herself and her unborn child. She wasn't looking for a handout from her distant cousin Roz, just a job at her thriving In the Garden nursery. What she found was a home surrounded by beauty and the best friends she's ever had-including Roz's son Harper. To Hayley's delight, her new daughter Lily has really taken to him. To Hayley's chagrin, she has begun to dream about Harper-as much more than a friend...
If Hayley gives in to her desire, she's afraid the foundation she's built with Harper will come tumbling down. Especially since she's begun to suspect that her feelings are no longer completely her own. Flashes of the past and erratic behavior make Hayley believe that the Harper Bride has found a way inside of her mind and body. It's time to put the Bride to rest once and for all, so Hayley can know her own heart again-and whether she's willing to risk it.
