In Between Breaths by J.L. Lennon

Tessa:
In between loss and living comes healing.
Before Jasper found her in the market in Manhattan, Tessa spent a year navigating a life without her brother or the man she loves. The dream she spent her life working towards no longer looked the same through the lens of a broken heart.
But she made a promise.

Jasper:
It was never a question of if, only when.
It took almost a year, but he’s in New York and they’re together and for that reason, and that reason alone it’s perfect right? No more secrets, no more hiding, they have a future.
He’s keeping his promises.
In between breaths…
They were lulled into thinking it was perfect.
Because being together was all that mattered.
But he’s losing her, losing himself… it’s time to go home.
And she’s holding her breath, afraid if she exhales he’ll disappear.
The forever they both want, the one he put on her finger while they dreamed of dogs and babies and promises kept, is threatened by the one thing she’s not sure she can give him. Home.
