Just on Porpoise (Hetta Coffey series Book 12) by Jinx Schwartz

Hetta Coffey is a sassy Texan with a snazzy yacht, and she’s not afraid to use it! Hetta, her dog, and parrot–along with a band of zany friends and frenemies–make for one rousing adventure after another. In Mexico’s Sea of Cortez, an endangered species is on the very precipice of total extinction, but taking on a vicious cartel to save a little porpoise might be a mite on the difficult side. Can they do it? The clock is ticking.
