Gus is a 13-year-old boy who thinks his two little sisters are aliens because they are always getting into mischief, eating his homework and tossing his things down the toilet, etc. They can't be human, he thinks. So, one day he had had all he could take and he ran away on his father's boat. A storm blew up and he was lost on an island with plenty of time to think. After realizing that he does love his sisters and misses them very much, his father finds him and takes him home. "My Two Alien Sisters" teaches children that people aren't always nice, but we can love them anyway. This book can easily be read by eight-year-olds and up, and may be read to younger children as well."
