In *Kingdom Come: Deliverance 2*, a crucial side quest, easily missed and impossible to revisit, involves retrieving Rosa's book. This guide ensures you don't miss out.
Unlocking Rosa's Book Side Quest
Before Rosa requests your assistance, complete the "Via Argentum" quest and begin "Taking French Leave." After resolving the Vavak situation with the Ruthard family (through force or diplomacy), speak with Rosa to learn about a secret passage into Maleshov, crucial for rescuing Hans. She'll then ask you to retrieve a specific book. Inquire about the book's identity and promise to deliver it to initiate "Rosa's Book."

Upon entering Maleshov, locate Hans in the tallest tower. Use the external stairs to access the tower's entrance. Inside, you'll find another staircase and a small kitchen. Wait in the kitchen until the guards above vacate the tower.

Rosa's book is located in the window alcove to the right of the fireplace—a red book. Retrieve it, updating your objective to return the book to Rosa.

Following the cutscene, continue "Taking French Leave." Despite Hans's initial reluctance to use the passage, you can progress towards a romance by selecting the dialogue option with a heart icon (provided you also chose the heart option in Trosky). Stealthily navigate to the stables north of Maleshov, subduing and hiding guards as needed. Once the path is clear, signal Hans to ensure his safe arrival at the stables.
A final cutscene concludes the quest after opening the gate. Return to Kuttenberg City and deliver Rosa's book to Ruthard Palace, completing the quest in Kingdom Come: Deliverance 2.
