In an alternate reality set in the early 20th century, the U.S. government has released wild hippos into the marshes of Louisiana as an alternative meat source. To no one's surprise, it is a ludicrous and disastrous idea.
The main character, Winslow Houndstooth, has lost everything and is driven by one thing: revenge. After the government hires Houndstooth, mercenary and part time hippo-wrangler, to clear the ferals from the marshes, he assembles a ragtag team of degenerates to help him out. Each member has their own specialty, hippo they ride on, and serious issues. The group must set aside old grudges and actively avoid being eaten alive to collect their payday.
This novel is as absurd as the summary makes it out to be, and I loved every second of it. From the first page, you can tell the author understands how ridiculous the story is and embraces it. I never knew I needed hippo-riding cowboy mercenaries in my life until River of Teeth by Sarah Gailey (2017) was put in my hands. It's a fantastic mix of classic western tropes with science fiction elements. It's a short novel, only about 175 pages, but it's long enough to fall in love with the characters and keep you laughing.
