We now rejoin The Zookeeper's Wife, already in progress.
It's 1941, and summer passes into autumn.
Then, on the next page, autumn passes into winter.
"All the Guests were spirited away to other winter safe houses" (18.4).
Keeping Antonina and Ryś company are a rabbit named Wicek (Vincent, in English) and a chicken named Kuba (Jacob).
The rambunctious rabbit terrorizes the house like a real-life Bugs Bunny.
In Spring 1942, Guests arrive at the zoo once more.
One of the Guests is Antonina's BFF from Chapter 3, Magdalena Gross.
Magdalena tries to avoid staying at the zoo for as long as she can, not because she doesn't like the zoo, but because she wants to live some semblance of a normal life.
That's impossible in Nazi-occupied Warsaw, so Magdalena eventually flees for the zoo.
