This quest is one of the Week 8 challenges in Fortnite, and asks you to collect Research Books at Holly Hedges and Pleasant Park.
The good news is that there are quite a few locations for these, and you probably won't have to battle too many rival players to collect them. However, they can be quite hard to spot.
Holly Hedges Research Books
In the green mansion, at the foot of the fireplace
In the beige house, south of town
The research book is located at the foot of the small library, in the entrance.
In the blue house
In the yellow house
Pleasant Park Research Books
Pleasant Park's first book is in the house that doesn't have the right shutters. The book is at the foot of a library, in the dining room.
In the big white house on the western side of town
You'll find the book in the living room, right next to the TV.
In the red brick house, north of town
This book is hidden behind the dining room table.
Remember that books are "indestructible" objects. There's nothing stopping you from picking them up later in a game, once initial drop skirmishes have ended.
