Danger in the deep blue sea / Dadey, Debbie

There's a shark in Trident City, and Pearl is so scared she needs a Shark Guard to protect her, plus she doesn't trust Kiki who isn't afraid of sharks, but Pearl goes too far when she accuses Kiki of stealing her necklace, in chapter-book format.

When a shark is spotted in Trident City, third-grade mergirl Pearl is terrified. Then to make matters worse, Pearl's special necklace goes missing. Pearl accuses another mergirl, Kiki, of stealing her necklace and says mean things about Kiki to get her in trouble. Only when Pearl has a dangerous encounter with a shark, does she see the value of her friend.
