My son (age 8) read the first Percy Jackson book this summer and developed a real interest in Greek mythology. Fortunately, my mother had hung on to my childhood copy of this book. I loved it then, and he loves it now--he read the whole thing this summer in the span of a week or two. Greek mythology is referenced so much in Western literature and this book covers it really well. The illustrations are great, and the writing is clear and accessible. Really a classic.
