Book 4 of the MONSTERSAURUS series.
Mombie the Mosasaur is always busy.
Every day, she swims the same route, fixes the same problems, and makes sure everything is done properly. By her.
She tells herself she is fine, even as small pieces of her begin to fall away. After all, stopping would mean asking for help, and Mombie doesn't need help from anyone. Or so she believes.
As the sea grows heavier and the work becomes harder, Mombie's determination turns into frustration, and her sharp words begin to push others away.
But when doing everything alone finally becomes impossible, Mombie must face a truth she's been avoiding: sometimes strength isn't about holding everything together by yourself.
