From award-winning author Deborah Heiligman comes Torpedoed, a true account of the attack and sinking of the passenger ship SS City of Benares, which was evacuating children from England during WWII. Amid the constant rain of German bombs and the escalating violence of World War II, British parents by the thousands chose to send their children out of the country: the wealthy, independently; the poor, through a government relocation program called CORB. In September 1940, passenger liner SS City of Benares set sail for Canada with one hundred children on board. When the war ships escorting the Benares departed, a German submarine torpedoed what became known as the Children's Ship. Out of tragedy, ordinary people became heroes. This is their story.

Where did the caterpillar go?

It seems to have disappeared, but it hasn't. It has turned into a butterfly! From the time a caterpillar first hatches, it eats so fast that its skin can't keep up. It sheds its skin several times as it grows bigger and bigger. Eventually it forms a shell around itself called a chrysalis. Nothing seems to happen for a long time. But then one day the chrysalis splits open, and a beautiful butterfly emerges. What a magical metamorphosis!

After a caterpillar comes to school in a jar, the children are captivated as it eats, grows, and eventually becomes a beautiful Painted Lady butterfly. This title features colorful illustrations from veteran illustrator Bari Weissman and lively text from National Book Award finalist and Michael L. Printz Honor winner Deborah Heiligman.

Both text and artwork were vetted for accuracy by Dr. Louis Sorkin, Senior Scientific Assistant at the American Museum of Natural History.

Most people think of mathematicians as solitary, working away in isolation. And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.
