In an overpopulated world where all signs of nature have been obliterated and a wall has been erected to keep out plague-ridden animals, twelve-year-old Mika refuses to believe that his twin sister was killed after being abducted, and continues to search for her in spite of the dangers he faces in doing so.

When his twin brother falls ill in the family's chateau in the independent republic of Geneva, sixteen-year-old Victor Frankenstein embarks on a quest to create the Elixir of Life described in an ancient text in the family's secret Biblioteka Obscura.
