In *Kingdom Come: Deliverance 2*, a crucial side quest involving Rosa’s book is easily missed, leading to a failed quest and potentially missed romance opportunities. This guide ensures you won't miss out.
Unlocking Rosa’s Book Side Quest
Before Rosa requests her book, complete the “Via Argentum” quest and begin “Taking French Leave.” After resolving the Vavak situation with the Ruthard family (through either force or diplomacy), speak with Rosa. She'll mention a secret passage to Maleshov, crucial for rescuing Hans. Inquiring about the book and promising to retrieve it initiates the “Rosa’s Book” quest. This quest is only available during “Taking French Leave.” Failing to find the book before leaving with Hans results in a failed quest.

Locating Rosa’s Book
Upon entering Maleshov, Hans is located in the tallest tower. Use the external stairs to access the tower. Inside, you’ll find more stairs and a small kitchen. Wait in the kitchen until the guards upstairs leave. Sneak upstairs to a room where Lady Ofka is seated. Knock her out, and collect the keys from her person, the podium, and the sword from the chest. Rosa’s book is a red book in a window alcove to the right of the fireplace. Take the book; your objective will update.


While there, grab the sword from the chest in the adjacent room. This provides the two weapons needed for Hans and his unexpected guest. Unlock the door on the left on the top level to trigger a cutscene.
Completing the Quest
After the cutscene, continue “Taking French Leave.” Guide Hans to the stables, clearing the path and ensuring his safe arrival. A final cutscene concludes the quest. Return to Kuttenberg City and deliver Rosa’s book to her at Ruthard Palace, completing the quest.
