Revenge is sweeter than regret...

Dublin. Calista is young, beautiful, and headstrong.

But Calista learns to survive. She knows she will find peace when she can finally seek retribution.

Madrid. Pilar grew up with very little means in rural Spain and finally escaped to a new life. Determined to leave poverty behind her, she plunges into a life of working hard and saving money. Enchanted by an older man, Pilar revels in their romance, her freedom, and accruing success. She's on the road to achieving her dreams. Yet there is one thing that she is still searching for, the one thing she knows will make her truly happy.

Sweeping across the lush European backdrops of Spain, Greece, and Ireland, The Years That Followed is a gripping, modern telling of a classic story. As two wronged women plot for revenge, their intricately crafted schemes send shockwaves through their families that will echo for many generations to come.
