Dreadnought (Nemesis #1) by April Daniels Book Review 23, Feb

DREADNOUGHT is the first novel of the Nemesis series. The premise is Danny Tozer, young transgender girl, is there when Dreadnought the world's greatest superhero is killed. Danny inherits the power of Dreadnought but also becomes her idealized self (effectively Supergirl). This is problematic since Danny is still hiding her trans identity from her transphobic parents as well as schoolmates. She is, after all, only fifteen. But there's more to her life than dealing with them. There's an entire army of evil she needs to defeat as the other superheroes have nothing on Dreadnought--and the world needs a Dreadnought.
