Adventure in Africa

by Connie Lee Berry

Ages 7-9  85 pages  Kid's Fun Press  December 2007

Adventure in Africa is written for children aged between 7 and 9 and may just be my favorite book in the Incredible Journey Series. In this book the two main characters Max and Sam are taken to an African Safari camp. Even with all the care taken by the staff to ensure the safety and comfort of the camp, things do go wrong and the two brothers find themselves rescuing an elephant and their tour guide, while braving the native wildlife and habitat of Africa.

Adventure in Africa is one of four books in this series of fluent readers’ paperback travel adventure books by Connie Lee Berry. The font(字体) is quite large and there are roughly a dozen maps, images and pictures in the book, which will attract younger readers. As an extra attraction, the back cover of the book lists some activities for children to do.

The animal photos were exciting, especially when the boys were able to ride an elephant! The pictures on the cover look like regular photos of family vacations. A large, interactive （互动的） companion website (www.ijbooks.com) allows readers to join in activities, contests and a club.

The price of the book is only ＄3.95 (US) now,＄1 lower than before, and Adventure in Africa is a bargain. Hurry up to order one.
