Before entering Bloodskal Barrow, but still in the Raven Rock Mine, the Dragonborn finds an altar which holds the book.

Read the book
The Dragonborn reads the book and is transported to the realm of Apocrypha.

The Dragonborn must then defeat the lurkers and seekers along the way until reaching another black book. Upon reading the book, three balls of green light appear, each corresponding to a new ability:

 * Lover's Insight or
 * Scholar's Insight

The Dragonborn then chooses one and is transported back to Raven Rock Mine.
