Down Too Deep by J. Daniels

Two single parents and three adorable kids are about to have a summer they’ll never forget in this sexy, heartwarming new novel of the New York Times bestselling series.
Following the sudden death of his wife, Nathan Bell 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 Nathan’s adorable two-year-old and wants to help Nathan however she can. As the days go by and her attraction to Nathan grows, she can’t help wondering what might happen if they became a family for real. 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 Jenna and her kids so much is losing them all.
