Leave with Katia on day 20 after collection all of her book materials. There are 11 in total.
One is always in your hideout in a closet.
The rest will be randomly placed throughout areas you can scavenge. 8 of them will be in random locations in lootable containers. The locations can be marked on your map by using Katia in the hideout to reveal locations. You don't have to have her reveal them in order to loot them but it makes it easier by cutting down on areas you need to check. Also in the first couple of days someone will come to the door asking for a bandage. Giving them one will reveal a location also.
The last 2 you have to purchase off traders. There are 4 traders in the game, they are in places you scavenge. They area in areas that say "possible trade". You can't get these one marked on the map so you might have to go to all 4 traders before you find the right 2.
After that just survive til day 20, and leave with Katia.
