Sometimes the Dead cling to life, striving to live again after their time as passed- often losing everything but that desire. Other spirits are prevented from passing on by necromancers, and bound to their will. [Sabriel scowls, fingers moving over the handles of her bells, feeling the mixture of Free and Charter magic within them.] And a handful of necromancers choose to trade life for power, becoming Dead Adepts. Thankfully, those are uncommon.
