This Time Tomorrow by Emma Straub

On the day Alice turns forty she reevaluates her life which is pretty much how she thought it would be except for her dad who is hanging on to life from a hospital bed. Since the beginning it has always been Alice and her dad after Alice's mom left Alice to be raised almost solely by Lawrence.
As if by some strange bit of kismet Alice wakes up in her dad's house not as a 40 year old but back as a 16 year old. Ironically, Lawrence is a children's book author who has had a very successful series of two brothers who time travel which allows him to accept his daughter's adventures. Now that she is back with her best friend, a healthy version of her dad, and has the means to change their lives will she make good use of the gift? Given chances to back doesn't mean Alice will know when to stop or which version is best. Time travel junkies will find much to ponder but also those daughters who wish for more time with their parents and the chance to say I love you and thanks for all of it. A heartbreaker, tearjerker ,thought provoking look at life and the paths we choose.  5 LibraryReads stars
