Love is a wonderful thing, and it doesn't have conditions in this novel about sister and brother Lenny and Davy as they deal with the fact that Davy is very different from everyone else around him. Davy is growing. And growing and growing. He is diagnosed with a rare form of gigantism. But he and Lenny are also trying to figure out where their father went, if they have a grandmother, what is going to be in the next issue of the encyclopaedia that is heading their way in the post and which letter is their favourite, as each one opens up the world to the siblings just a bit more.
