You Make My Heart Stop — Becky Hunter

A young woman must decide between her life on earth and her soulmate -- who she can only be with in the afterlife -- in this poignant exploration of loss, love, and fate that is perfect for fans of Kirsty Greenwood and Jojo Moyes.
 
For years, Emery has lived with a condition that means her heart could literally stop at any second. While her friends and family try too hard to protect her, Emery refuses to live in perpetual fear. Besides, she has a secret -- when her heart stops, Emery actually dies . . . and that's the only time she can see Nick.

Nick is Emery's constant -- the man who exists in the space between life and death, helping souls cross over to whatever comes next. Usually, he meets people just once and for a fleeting moment. But Emery and Nick keep meeting, keep tilting each other's worlds and pushing the limits of their time together.

Every brush with death brings Emery closer to a soulmate she can never have while she remains alive. Yet the universe seems determined to prove it still has a few surprises left for her -- first kisses, second chances, and unexpected, world-changing opportunities. Emery could finally have a chance at a real future, but how can she give up the love of her afterlife to seize the life she has now?
