This volume is part of an integral that has at the time of writing 25 volumes, each comprising a minimum of five full stories which the majority has a twenty pages. One judge from this abundant production is like trying to judge the quality of a wine through one gulp swallowed quickly. In this Volume 18, Rahan meeting Naouna becomes dog-man, drugged slave, invented surfing, gliding ... questions the dead. Each story has its share of fights, creativity, friendship, reconciliation and love to dear hero. Only the last story (The first fair 15 pages) seems largely superior to previous although the drawing is coarser (Romero designer) but may be this is due to a bad copy of an old album.
