i recently read this book after hearing from many, many ppl abotu its greatness, and i must say, they were not wrong.

however, im wondering if theres supposed to be like a second volume or soemthing that i dont know about. does it really end with them escaping magrathea (the lost planet) and then going to lunch at the restaurant at the end of the universe? i was hoping for an explanation about alot of the stuff....like who actually runs teh galaxy, and why zaphod beblebrox (sp) messed with his own brain?

if tehres like some wierd secret 2nd part to it, plz let me know.
