The story of Gwen Dylan (aka Gwendolyn Price), the grave digging zombie, continues in volume 2 of the collected iZombie. The plot thickens, and there is a bit more back story about Gwen, her friend Scott, her prospective beau Horatio and the mysterious Amon.
Volume 2 opens with a scene from Gwen's past, before her death and subsequent resurrection, which introduces her old friend Tricia. When one of the brains Gwen eats turns out to be that of Tricia's mother, Gwen finds herself driven to pass on the woman's message of reconcillation to her daughter. The trouble is that Tricia is sure to recognise Gwen and know that's she's supposed to be dead, so appearing to her will require some explanation.
Meanwhile Scott is dealing with the death of his grandfather, but this town being the spooky place that it is, the old man is not really gone but instead hanging around in spirit and possessing the body of a chimpanzee. Scott also has a run in with Gwen's brother, a potential future love interest for the shy were terrier. Horatio, Gwen's love interest and member of a supernatural hit squad finally comes up against the vampires from Bloodsports Paintball, who have a proposal for him which surprisngly does not involve his immediate demise. Amon, the former Egyptian mummy now revenant Gwen met in the previous book has met up with Galatea, an old flame with a plan to bring forth some sort of demon or god from another dimension and try to control it, which strikes Amon as a very bad idea.
There are quite a few different plot threads going on, which might make iZombie confusing if you were reading it one issue at a time instead of in collected volumes. There is a lot to keep you interested, with plenty of secrets still to be revealed. For example, we still don't know how Gwen died (Gwen herself does not remember), nor exactly what Amon believes she will eventually have to do if she wants to stop losing her memories.
I will definitely be picking up iZombie Volume 3: Six Feet Under and Rising.
