Sixteen-year-old friends Red, Leo, Rose, & Naomi are misfits; still figuring out who they are & who they want to be.
Miranda is no ordinary mermaid. She has short, spiky hair dyed seaweed green, & she never sings to sailors. When a suspicious-looking man called Gus Grabbit puts up a FOR SALE sign on their rock, Miranda is horrified & hatches a plan. She gathers together the other mermaids & her underwater friends, who prepare to take action, & fast!
