Meet Lucy. Horribly burned in a house fire while she was a child Lucy was forced to undergo a radical treatment in order to safe her life. However, this treatment would have far greater consequences then just saving her life as it would change her in ways that none had foreseen. Now she must learn to deal with her ever shrinking world as she grows from a child to an adult while trying to retain her humanity even as her power continues to expand.

In order to help her with these task is her friends and family including her childhood friend and romantic interesting Albert.

 Though if you want to jump strait to the giantess content I'd suggest going to chapter three. Lucy's a young woman by then and well into the giantess category though I wouldn't say quite a mega.

A girl named Alyssa is a normal girl, unless being a giantess doesn't count. This book will transition into a diary later on.
