City of Secrets (Hardcover)

From the Publisher: Set in Talia, a parallel-world version of Italy, the Stravaganza series combines Renaissance court intrigue with time travel, subterfuge, romance, and revenge.  In this new story arc, we meet Matt, a painfully dyslexic and insecure boy (despite a beautiful and clever girlfriend!). Matt has just discovered that he is a Stravagante - someone capable of traveling between two worlds. A leather-bound book transports Matt from our world to Talia, where he meets Luciano.  Luciano has killed the head of the powerful di Chimici family in a duel, and has gone into hiding. The di Chimici are on the verge of making a terrifying breakthrough into our world, and it will fall to Matt, Luciano, and the other Stravaganti to stop them….
