Birds of Prey (Renaissance), book 5 : Soul Crisis
Christy Marx et Collectif2015

A new mission... And a deadly new nemesis!

The Birds of Prey have faced terrible betrayals and tragedies, but their luck is about to change. Kurt Lance, the husband who Black Canary thought was dead, has been discovered alive but comatose. In the midst of this shocking news, the Birds have been taken in by a mysterious new benefactor in their struggle against evil: her name is Mother Eve, and she's lived for millennia as a force for good.

But now Mother Eve needs help in her own ancient battle...against her fellow immortal, Ra's al Ghul!

Ra's has an offer for the Birds, as well. He can grant Black Canary her heart's fondest desire-the revitalization of her husband-and all she has to do is betray Mother Eve. Can Batgirl, Strix and Condor hold back the League of Shadows and protect their benefactor, or will it come down to Black Canary and an impossible decision?
