The Death of Oracle (7-10). This is a much more sensical arc than the ones in the previous book. It's a really nice confrontation between Oracle & the Calculator that closes off plots many issues old and also a big status quo change that really makes sense [7/10]. 
 Which Reason Knows Not Of (11). This Huntress/Catman teamup is great for its characterization of both of them and for its emotional ending [8/10]. 
 Hostile Takeover (12-13). Unfortunately, Simone's finale for Birds of Prey is lack-luster. It's somewhat incoherent and continues plots from Secret Six rather than anything of its own. Worst, the ending is really a non-ending. Still, parts of the caper are fun [6/10]. 
 War and Remembrance (14-15). The final story is even worse (and not by Simone!). It's actually got some nice background on Canary and Phantom Woman as legacy heroes, but the foreground story has little depth [4/10]. 
 This volume would have been better if it'd just ended after the death of Oracle ..
