Lawn Boy by Gary Paulsen
In his book Lawn Boy, Gary Paulsen has done a wonderful job of capturing an everyday job for a tween boy--like mowing the lawn--and expanding it into a hilarious summer experience.
Lawn Boy is a great book for boys, but I think girls will enjoy it, too. Paulsen elaborates on experiences most all teens can relate to--like not having any money and being bored during summer vacation. They’re too young to drive but not that interested in toys, unless you consider video games toys. And if they want to get new video games to play, they have to come up with the funds to buy them.
Their parents are happy because they aren’t sitting in front of the computer screen or TV. They are doing “something” outside the house and they are earning their own money! But for our character, his little lawn-mowing business turns into a lot of cash with hilarious consequences. His employees include a down-on-his-luck prize fighter, an accountant, and some others with possibly shady backgrounds. It's a great read, and the sequel is out as an eBook so check it out, too: Lawn Boy Returns.
