Miami!

When Zia Donatella comes to live with the Bertolizzi family, little do Alfie and his older sister, Emilia, know what's in store for them. Zia Donatella is determined to show them how a home-cooked meal is better than even the best takeout pizza. And when Zia's plan actually transports Alfie and Emilia to famous food cities around the world, they learn firsthand how food can not only take you places but also bring you back home. 
 
In the seventh book in the series, Zia turns up the heat when her secret ingredient sends the siblings to the "Magic City" - Miami, Florida! When they get there, they cook up an unforgettable adventure full of beautiful beaches, salsa dancing, and deliciously spicy Caribbean food.
