"The Garden of Mysterious Flowers" is a story about the lost connection between sisters, who find their roots by traveling between the canals of Amsterdam, English gardens, and lush Tuscan hills. Iris Donati can’t imagine her life without plants: it’s they who give her the feeling of home she never had—since her father and she kept moving from place to place. Of course, she can’t miss the world’s biggest flower exhibition, where she unexpectedly meets a girl named Viola, who looks exactly like her. The sisters want to find out why they were separated, and they knew nothing about each other. To solve the mystery, they set off for Italy, a medieval town where, among cypress alleys and green slopes, there is an old house surrounded by an endless garden. Here they will have to save the garden, unravel a secret rooted in the past of the Donati family, and find true happiness.
