Lenny, small and sharp, has a younger brother Davey who won't stop growing - and at seven is as tall as a man. Raised by their single mother, who works two jobs and is made almost entirely out of worries, they have food and a roof over their heads, but not much else.
The bright spot every week is the arrival of the latest issue of Burrell's Build-It-at-Home Encyclopedia. Through the encyclopedia, Lenny and Davey experience the wonders of the world - beetles, birds, quasars, quartz - and dream about a life of freedom and adventure, visiting places like Saskatchewan and Yellowknife, and the gleaming lakes of the Northwest Territories. But as her brother's health deteriorates, Lenny comes to accept the inevitable truth; Davey will never make it to Great Bear Lake.
