Bree cant wait for her first day at her new middle school, Enith Brigitha, home to the Mighty Manateesuntil shes stuck with the only elective that fits her schedule, the dreaded Swim 101. The thought of swimming makes Bree more than a little queasy, yet shes forced to dive headfirst into one of her greatest fears. Lucky for her, Etta, an elderly occupant of her apartment building and former swim team captain, is willing to help.With Ettas training and a lot of hard work, Bree suddenly finds her swim-crazed community counting on her to turn the schools failing team around. But thats easier said than done, especially when their rival, the prestigious Holyoke Prep, has everything they need to leave the Mighty Manatees in their wake.
