A travelogue for middle readers, much in the spirit of an adult travelogue but with full-color pictures and a child-friendly emphasis on camels, unusual people, outsize weather and benign adventure. Raskin's journey was inspired by a signpost in Morocco which read "Timbuktu 52 Days". He sets out from Fez and ends up (52 days later?) in Timbuktu, whence he continues on to the salt mines of Taoudenni, Mali.  (NAF11, $14.95)
