the summer of the swans- betsy byars

this book was pretty good, and is short so you don't have to spend weeks reading it. the main character's name is Sara. she has a younger brother, charlie, who is mentally handicapped and hasn't talked since he was 3 years old (he's ten). also, sara has a beautiful older sister, wanda, who she is jealous of for so many things. wanda is 19 years old, and is just really pretty. sara, however, is tall, skinny, has huge feet and ugly orange- dyed sneakers. everything up until her fourteenth summer had gone great, and just glided like the swans on the lake. but one day, sara wakes up to her bossie aunt willie telling her to get charlie for breakfast. he's not in his room. he's not in the washroom. he's not in the house! where could this tiny- for-his-age ten year old who was unable to speak have gone? is he even able to call for help? does he need help? where is he?!
