Book excerpt: Inside a room kept secret from even his closest friends and family, Reed Richards had scrawled upon the walls 100 of the biggest and boldest ideas his brain could produce. And, recently, he added a 101st, the most audacious ever: "Solve everything." It would be a mantra that would lead the obsessively intellectual Mr. Fantastic to doing great works on behalf of humanity - and, in typically fantastic fashion, lead him into even greater trouble! For, as the big brain of the Fantastic Four will find out, solving everything carries with it a great cost, and one that is perhaps too much to pay.
