The Memory Bank — Carolyn Coman

THE MEMORY BANK is the story of Hope Scroggins, who lives with her beloved sister Honey and the Dursley-esque parents they share. In fact these parents are SO horribly awful that one day, when the sisters disobey the rule against "no laughing", they banish Honey forever, telling Hope that she must simply "forget" her.

Hope knows that she HAS to find her sister again, before her memories of Honey fade. But before she can even begin to look, she's whisked away to the World Wide Memory Bank, where her accounts are in disarray...

There she learns about the process of how dreams and memories are kept safe. She also learns that there's a group of misfits called the Clean Slate Gang who want to destroy the Memory Bank, and all of the dreams and memories kept there. What she doesn't know is that Honey has been picked up by the Clean Slate Gang, and they're heading right for the Memory Bank.

The story of how Hope makes her way through this brewing conflict and rescues her little sister is full of tension and suspense, set in a vividly imagined world of strange machines and wonderful characters.
