By the Numbers When Nathaniel, aka Deuce, arrives home to an apartment building on fire, he can only think of one thing: his pregnant dog. Luckily firefighter Trey Donovan rescues her, and Nathaniel is exceedingly grateful. In fact, he tracks down Trey's station so he can show his gratitude properly-and explore the connection he senses between them. Trey's interested, but a less-than-friendly ex-wife and the seven-year-old daughter he's raising make things… complicated. Between everything on Trey's plate and the newborn puppies Deuce must care for-while homeless-finding common ground won't be easy. But the spark of attraction between them is too enticing to be allowed to fizzle. Adding It Up Dogs, a young daughter, and shift work make for an unpredictable and never boring life for new couple Deuce and Trey. Trey is keeping his ex-wife out of their hair, but Deuce is determined to forge a truce between them all. Trey is vehemently opposed to a friendship between Deuce and Holly-she's the last person Trey wants more interaction with. Deuce persists, however, and tensions between them could spell the end of their relationship. They'll have to find a way to make it all add up again-or lose everything.
