This Too Shall Pass by Milena Busquets. The book is being released by Hogarth on May 24, 2016.
Amazon says this about the book: Blanca is forty years old and motherless. Shaken by the unexpected death of the most important person in her life, she suddenly realizes that she has no idea what her future will look like.
To ease her dizzying grief and confusion, Blanca turns to her dearest friends, her closest family, and a change of scenery. Leaving Barcelona behind, she returns to Cadaqués on the coast, accompanied by her two sons, two ex-husbands, and two best friends, and makes a plan to meet her married lover for a few stolen moments as well. Surrounded by those she loves most, she spends the summer in an impossibly beautiful place, finding ways to reconnect and understand what it means to truly, happily live on her own terms, just as her mother would have wanted.
A fresh, honest, and ruefully funny story about love, sex, marriage, grief, friendship and parenthood, THIS TOO SHALL PASS is an irresistible novel that is fast becoming an international phenomenon.
