In this book, Riley goes to Madagascar to look for lemurs with his Uncle Max and Aunt Martha. In Madagascar, Riley learns about various plants and animals in the jungle, including the baobab tree, the Parson's Chameleon, and the shy Fossa.

Riley accompanies his aunt and uncle into the jungle to look for the elusive aye-aye, which is a seldom-seen lemur, but they have no luck. Then, when he returns to his cabin, he sees two faint lights outside his window, and there it is, the aye-aye.

When Riley returns to school, he shares the richness of Madagascar with his classmates.

The book is well researched and includes real photographs interspersed with the illustrations. Information boxes appear throughout and give more information about the plants, animals, and characteristics of Madagascar. For example, we learn from a research scientist that eight out of every ten creatures in Madagascar exist nowhere else on earth; and from an ecologist, we learn that the aye-aye has a long, bony middle finger which lets it spear grubs and insects deep inside of wood.

The combination of illustrations, photographs, and facts with the adventure setting make this a worthwhile book for young readers. There is even a sticker that can be placed in Riley's passport, so that the reader can keep track of each adventure.

This is an excellent educational book, and I give it four stars.
