SEPTEMBER Our two flagship books this month are both for cyclists - albeit very different cyclists. The first is from Wavefinder 'Mountain Biking The Manual' a reference manual designed for riders of all abilities and secondly 'Where to Ride London' an extremely practical guide for cyclists of all ages to the safer areas of the capital. Aside from these Harveys have added two new maps to their range, a Mountain Map for Snowdonia South and a map for the Cleveland Way. If you need something to capture the imagination we have now sourced a map to the Tsum Valley. With access restricted until 2008 this sacred pilgrimage valley is now open, the map will put the location in context.

Here are our bestsellers of the moment. There are the all-time favourites alongside a selection from the best of some of the new generation of outdoor publishers. What they all have in common is that they are published by enthusiasts and experts.
