A non-spoiler 'epilogue' for my romantic fantasy trilogy.

Praise

My YA loving heart loved this book! Fantasy Sci Fi! The book started and just threw you straight into the world, not a soft fluffy cushy place to land either! I believe that teens would really enjoy this book the main characters are relatable, the story moves fast, there is no cliff hanger. Very light romance throughout.

I had the privilege of reading Son of Osirius as an ARC, and it completely pulled me in. The world feels expansive and alive, with vivid detail that never bogs down the story. The characters are complex and emotionally grounded, which makes the stakes hit even harder. And the flying cats? Majestic is the only word for them.

I’ve always been a huge fan of dystopian sci-fi and movies like James Cameron’s Avatar, so when I heard that Cathryn DeVries’ Son of Osivirius fit the bill, I had to see for myself. Sure enough, the book comes packed to the brim with gorgeously imagined locales, spirited characters, and a healthy dose of evil governments in need of overthrowing.
