The final part in Constance Verity's epic adventure: saving the world is easy. Everything that comes after is the tricky part. Look out for Crazy Rich Asians superstar Awkwafina as Connie in the major movie adaptation of the first book.

Saving the world is easy for Constance Verity: she's used to doing the impossible on a daily basis. Everything that comes after is the tricky part.

Connie has accepted and secured her place in the universe. There isn't a foe she can't outfight or a peril she can't outwit - until she discovers she herself might be the greatest threat to the world she's spent her life saving.

All the signs are pointing to impending doom, and not just for Connie. Her friends, her enemies and the universe itself are all at risk. She's always known she was destined for a glorious death, but she never suspected she'd be taking everyone and everything else with her.

With her trademark determination, Constance Verity sets out to avert a cosmic plan millions of years in the making - and save the universe from herself.

After all, who else is going to do it?
