After the death of her husband, Abi Hartwell Acosta poured her heart and soul into two things: her son and her family ranch. Hartwell Hills Ranch is her home, and Abi is the sunshine to everyone on it. With the responsibilities of the ranch falling to her more and more, she's finding it harder to wear that happy face all the time, especially when an old 'friend' shows up, bringing way too many memories with him.

Cash Callahan is the epitome of the saying 'when push comes to shove'. Everything in his life fell apart after his best friend died: his career, his marriage...the friendship he valued more than anything. He never thought he'd find himself back at Hartwell Hills Ranch, but when the opportunity pops up for him to use the training arena, he can't say no. Even if that means he'd finally see Abi after assuming he'd lost her forever.

Tensions rise as Abi and Cash find themselves battling for the same space, one that isn't big enough for all the feelings they've been bottling up over the past five years. Can they find a way back to each other? Or will they finally realize that neither of them ever truly left the other behind?
