I just finished Convergence and I'll be sinking my teeth in Unbound shortly. Thoroughly enjoyed every bit of it. I should say I preferred the design and voice of Rosa in Legacy.
The only thing that upset me a bit is that Joey only cares about Rosa's fate because he's afraid he'll have to spend time hanging around in the hospital. That was OK when they had just met, but later... dunno, I guess I expected them to bond. It's a bit weird if Al doesn't care for Sam
