Raised by her literary icon father Carson Wells, Alison Wells always felt loved, even though her mother died when she was a teen. But when she takes a DNA test on a whim and discovers she has a sister she never knew about, it’s clear there are things her father didn't tell her before he died. Determined to meet Juniper—her half sister—and unravel the truth of what happened all those years ago, Ali finds herself taking a job as Juniper’s intern. She’ll eventually figure out a way to tell Juniper the truth of their relationship. But she never could have imagined what would happen next…

Juniper Connolly has always been incredibly healthy… until she wakes up in the hospital after experiencing cardiac arrest, with her new—and recently fired—intern to thank for saving her life. It’s clear June needs to de-stress her life a little, so when Ali offers her the use of her family’s cabin in a small Wyoming town, June has no reason not to go. But when she arrives, her life will never be the same.

Under the wide-open spaces of the Wyoming summer sun, Ali and June will untangle the secrets and lies their lives were built on to discover who they really are and what family really means. But even more than that, they'll build a real relationship with one another and finally become sisters.
