Down too deep / J. Daniels.

"Following the sudden death of his wife, Nathan Bell has spent nearly two years burying himself in work and neglecting his biggest responsibility: his daughter. Overcome with guilt, he wants to connect with little Marley, but he doesn’t know how to do it alone. And then Jenna Savage throws him a lifeline. A single mom of twins, Jenna is more than capable of taking care of Nate’s adorable two-year-old, and wants to help Nathan however she can. Soon, attachments are made, forcing Jenna and her kids into new territory. And the closer everyone becomes, the more right it feels. Falling in love forces Nathan to face his biggest fear, and when hearts, both big and little, are on the line, the only thing scarier than needing someone is losing them all."--Publisher description.
