The Lost Book of First Loves: A Small-Town Contemporary Romance Novel about Two Sisters Discovering Family Secrets

From New York Times bestselling author RaeAnne Thayne comes a brand-new story about two women, a family secret and a lost manuscript that changes everything...

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.

Don't miss SNOW KISSED by RaeAnne Thayne--a cozy holiday romance about a single mom, a borrowed date, and the kind of Christmas magic that turns a simple deal into something real

RaeAnne Thayne just became an author I will keep my eye on after reading The Lost Book of First Loves. The story offers character growth, some mild suspense regarding the mystery of their father, and a slow-burn romance with some humor sprinkled in.

I cared about the characters and wanted to know how the story would unfold. While I usually like some on-page intimacy in my romance books, there’s so many layers to the book that I didn’t feel anything was lacking.

Overall, readers who enjoy women’s fiction or contemporary genres, and love a good laugh with some introspective themes, I guarantee The Lost Book of First Loves will hit the spot.
