An excellent sourcebook for players and DMs wishing to add more depth to the warlock class. I especially like how ALL of the material in this book integrates seamlessly with the official rules without making the warlock overpowered. My favorite aspect of the book are the marks and boons for existing archetypes. They add a fun flare to roleplaying without changing any of the basic elements of the class. The new evocations are good too - well thought out and balanced.
