Mist, metal, and ash

"In an alternate 19th-century Italy, Elsa has an incredible gift: she can craft new worlds with precise lines of script written in books. But political extremists have stolen the most dangerous book ever scribed--one that can rewrite the Earth itself. Now Elsa must track down the friend who betrayed her and recover the book before its destructive power is unleashed. Can she handle the secrets she'll uncover along the way--including the ones hiding in her own heart?"--Provided by publisher.
