A good book to support science units on life-cycles or habitats/conservation.  It’s officially classified as fiction, as the bulk of the book is a picture book telling the story of a boy and his family working together on a rainy night to watch for spotted salamanders crossing the road on their way to lay eggs in the pool where they were born.  They count the salamanders they spot, warn approaching vehicles to be careful, and help the salamanders across the road.  In the back there is a lot of non-fiction supportive information to explain the life cycle of the salamanders, and efforts being made in many communities to help protect them.  The glossary gives clear and simple definitions to important words that may be unfamiliar to readers.
