..go and get it, it's a wonderful book. It is completely rewritten, and has more than 1500 color pictures (no more white/black ones) - second edition had around 500 (in colour). Nearly all known species of geckos are pictured (with some exceptions) in excellent quality, e.g it features pictures of Uroplatus alluaudi, malahelo, Paragehyra spp., Matoatoa, undescribed Paroedura, Microscalabotes and so on.
