Infectious Virtual Yowberry
Ivy Sierra and cat Frank are mutated into Yowberries - telepathic internet organisms.
Ma$$ hunt Ivy for her Yowberry DNA; her missing parents' gift.
Ivy runs with Twisted Woman in unpredictable Escheresque subways, plankton blizzards, DevilTongueValley, cybernite and fleewholes.
When Ma$$ catch Ivy's gran, button-phobic Nina and kid detective Spencer, help.
Finding her parents costs death.
