Caesar

Were Zoo #23

by R.E. Butler

Alpha lion Caesar has everything…except a mate by his side. Then jaguar shifter Sera arrives with danger on her heels, and his animal snaps to attention with a single demand—mine.

After sacrificing everything to help her daughter escape a forced mating, Sera is only looking for safety at the safari park. But Caesar is impossible to ignore—powerful, protective, and so tempting it hurts.

When the jaguar alpha shows up with plans to use Sera to retain control of his people, Caesar will show him why alpha lions are the most dangerous males on the planet when their soulmates are threatened.

All hail the king.

Yay for a good story and happy ending!!

Otto is deranged enough to not give up and causes quite a few issues for everyone at the park.

Despite all the troubles, Caesar and Sera do their best to continue to live life, long awaited dreams start becoming reality, and our favorite moose makes a great appearance in this book!

Can’t wait for the next one in this series!!!

This series just keeps getting better! Book 23 takes everything I love about the Were Zoo series and elevates it even further. From the powerful alpha lion Caesar to jaguar shifter Sera, the chemistry, suspense, and adventure kept me completely hooked.

I loved how the story balanced danger, romance, and the intensity of the mating bond. The stakes were high, the emotions were real, and the characters’ journey was deeply engaging. RE Butler knows how to connect her readers to the characters’ struggles and triumphs, making every moment feel earned.

This story didn’t just meet my expectations! it exceeded them. I’m already excited to see what she writes next. Chef’s kiss!

I love this story. Sera has escaped her former pride. She meets her meets her mate Caesar. Her old alpha is dangerous. He wants Sera back at all cost. I love how Caesar, his pride and the zoo come together to protect family. Caesar’s and Sera’s story is awesome. I love this series, I cannot wait to read more.

I was delighted to finally have Caesar and Sera's story. There are lots of sweet moments, but there is a ton of action and plenty of bad guys to deal with before they can relax. I loved that, once again, the entire park bands together to protect one of their own.
Highly recommended author and series
