This is a hit and miss, I think, but for the most part, it's a hit with me. The premise is really to set up Batman and his arch-nemesis, Ra's al Ghul as allies in defeating a common enemy, mainly the latter's, known as Qayin.
Meanwhile Ra's' daughter, Talia and Bruce rekindle their romance (such as it is) and consummate their "marriage". Surely enough, Talia is with child soon after, leaving Bruce to consider his true priorities, and giving Talia no other choice but to do as she knows is right.
I'm not exactly repulsed by the Talia/Batman relationship; I can very well see the attraction there is between them, but it's all it is really. Certainly Batman doesn't really consider Talia his equal, not when she's always her father's puppet, and she is constantly torn between her loyalties to her father and to her "beloved". Admittedly it's kind of easy to forget that Bruce isn't a loveless, sexless being—he is a man, after all (but let's not get into the whole arrested development idea). I was happy, albeit wary, that Bruce seemed to have found some comfort and love with Talia. This happiness is short-lived, not surprisingly. It's a rather poignant end.
Anyhow, this is a nice (and dated, if the Cold War overtones are any indication) little story of Batman's relationships with the al Ghuls that has now been retconned in the current canon. The art is easy on the eye too—the sequences flow really quite nicely, better than they usually are now!
