When Dean agrees to escort his roommate Cassie back home for a family wedding, he has no idea what he's in for. Oh, he knows Cassie is being pursued by a neighboring family to join their businesses in some sort of marriage-merger and she's not interested -- but he's in for lots of surprises from Cassie's family. 
 Cassie's brother Callum helps the family run the Shady Pines hunting reserve. There's his father, two brothers and his grandmother all trying to keep the family business afloat. Callum is dedicated to his family, works hard, but he is living a lie. He doesn't feel comfortable revealing to his family that he's gay. He's ultra-sensitive to the impact that revelation might have on his family and their business. 
 But when Dean shows up at Shady Pines, his carefully constructed life gets thrown for a loop. There's an immediate attraction between Callum and Dean, although at the start it plays out with a lot of tension. 
 Callum and Dean are an unlikely pair, with Dean being a city-boy and all, and Callum keeping secrets. But these two just work so well together, and I loved the gradually falling-in-love between these two. It's sweet and sexy (and hot, hot, hot!) 
 There's a great supporting cast and intriguing secondary storylines to this as well. I loved the Montgomery family, especially how they worked the land and tried to keep the family business going. 
 This book kept me turning the pages until the very end and it's a lovely testament to making relationships work in spite of the challenges. 
 Everything in The Deepest Blue hit the right note for me. This is definitely one of my favorite M/M titles of 2015. Recommended.
