Although several have tried, I don't think anyone has managed to capture the spirit of Tin-Tin quite like Garen Ewing in his Rainbow Orchid books. Following the adventures of Julius Chancer, historical researcher, and his search for the mystical Rainbow Orchid, the series has received wide-spread acclaim (see here for The Guardian review of the third volume of the series). Now we have The Complete Rainbow Orchid (Egmont) which collects all three volumes and also includes 14 pages of sketches, research and notes. Explore more on the official website (see here) and watch out for Ewing's occasional contributions to The Phoenix Magazine. Highly recommended for all ages.
