The Last Star in the Void

The brilliant conclusion to Melissa Caruso's Echo Archives trilogy; a whip-smart adventure fantasy where a detective has to solve the greatest mystery of all--her own murder.

Kembral Thorne is back on the job. Everything is going great--she hasn't been in mortal peril for months, her daughter is learning to crawl, and she's thinking about getting serious with her girlfriend, cat burglar Rika Nonesuch. But then a simple mission goes wrong, and a mysterious Echo hires her for her most dangerous case yet.

This time, the murder Kembral must solve is her own.

Her first warning: Watch out above you. It won't be her last. The cryptic messages give Kem an edge against her would-be murderer--but there's more at stake than her own survival.

Rips in the very fabric of reality are spreading through the Echoes, and Kem's blood is the only thing that can close them. A traitor among her allies is willing to kill to stop her. To save all the worlds, Kem must figure out who she can trust--and Rika must decide how much of her humanity she'll sacrifice for the power to protect the woman she loves.
