This is Phil and Kaja Foglio's novelisation of their ongoing Girl Genius webcomic (or rather, the first three volumes of it). The webcomic promises 'Adventure, Romance, Mad Science!' - and that's exactly what you get in this book. It's a lighthearted, fun romp through a world shaped by mad geniuses (those with 'the Spark') and their crazy inventions.If you already read and love the webcomic, the book won't offer any surprises in terms of plot, but what it does is flesh out the characters and offer more details, along with some backstory. I heartily recommend it.If you don't already read the webcomic, but you're into steampunk (or as Kaja Foglio prefers to call it, gaslamp fantasy), then I recommend both webcomic and book. Both tell the same story, so pick your preferred medium. Or do as I did, and read both!
