As children, they vowed to be together forever, but people evolve. Can they mend the shattered promises of their past and earn the second chance they deserve?

Perry “Puma” Steel has ended his contract with his special op's unit, seeking one goal: to run his own ranch in the Colorado mountains and start Shades of Steele Security. The mission is to protect, but Puma didn’t expect to become the guardian of someone from his past—someone he's never truly gotten over. Someone who could soften his rough edges.

Bryar LeGuard finds herself in a dangerous situation. She has ruffled a criminal's feathers, jeopardizing her life. Now he wants her dead. Fearing for her safety, and her family, she has no choice but to seek the protection of the one man she swore she would never see again—her ex-husband. They are enemies...but are they?

Both have transformed from the young sweethearts who once promised each other forever. Puma is now war-hardened and rough around the edges, while Bryar is damaged and tends to sabotage any chance at love. He may be the only one who can save her—not just from the threat against her life, but from her painful past. His lips and touch bring her bliss but forgiving him for breaking her heart may be a formidable challenge.

The clock is ticking. Puma must save her before he loses her for the second time. Or is she saving him? He will give his life to protect her, and it might come down to just that.
