From publisher blurb:
The Lost emerge from maddened Arcadia not wholly human; composed of raw elements and even stranger stuff, they are all also deeply emotional. Divided into Courts that correspond with seasons as well as emotions, they learn to harvest Glamour from mortals. But they are not limited to just fueling their Contracts and powering their Tokens; emotions can be used to work magic similar to that found within the Hedge and beyond. Any changeling brave, or desperate, enough can attempt to call upon her emotional connections of her Court to channel Glamour into magic both wondrous and dangerous.
Inside you’ll find these features for Changeling: The Lost, 2nd ed.:
An optional system of channeling emotions to perform magical feats.
Five new kiths including the predatory Lamia and the haggling Jinn.
Contracts, both revised and new, to add more options for changelings of all Courts and Seemings.
