Hello! I sneaked into the pages of this book - uninvited, of course - because I love crosswords and quizzes, with the condition that they don't have... cats in them.

The exercises were created by playing with Leonidas, Margarita, Vangelis, and Angela, the quadruplets of Mr. Giannis and Mrs. Nelli, who have finished the 4th grade.

Now, how these exercises became a book is a story you'll learn by flipping through it.
