This book is almost completely Scarred Lands fluff text. There are backgrounds and flavor text for every combination of cleric and god, druid and titan, as well as page upon page of religous dogma. If you are a HUGE fan of the Scarred Lands you might like this but I was looking for some new crunchy bits to make clerics and druids more interesting.
All the stuff of any use to me was in the back appendices. They are few divine feats for clerics [turn attempt converts to ability X]. But the useful feats and spells for druids are even thinner. There is a group of totem feats but they didn't really grab my attention.
The file size may be over 8 meg but I think there was only around 1.5 meg that wasn't fluff text. I won't be getting any of the other player's guides.
