My life is perfectly fine.

Alex has pretended this for years―despite an emotionally absent father, a best friend drifting away, and a floundering dog-training business. At least Alex has her sister, Meredith, a driven polar opposite. But both their lives are upended when their estranged mother dies of a genetic condition that the sisters have a fifty-fifty chance of inheriting. For Alex, a world without her mother is uncomfortable. But a world without Meredith is unthinkable.

Alex suggests a pact to which Meredith tentatively agrees: In three months they’ll get tested. Until then they go after everything they’ve ever wanted. Alex is finally stepping out of her comfort zone and opening herself up to new relationships. Or maybe reconnecting with an old one. Nathan, a boy who once broke her heart, needs a trainer for his mixed-breed rescue. Alex can’t resist.

As sparks rekindle, and time passes much too quickly, Alex discovers more about herself, her sister, and her mother than she ever imagined. And that everything in life―especially happiness―comes with a risk worth taking.
