The Laboratory of Good and Evil Knowledge is full of mystery, weird science, and very clever girl named Aleeza who is trapped inside. There are dark corridors, and a missing best friend who happens to be a snake.

This story is about understanding that the world isn't meant to be perfectly organized in your head. Sometimes, you just have to let it happen, and when you miss someone, the best thing to do is to carry them with you in a new, creative way (like wearing a rubber tube as a fake snake, genius, right?). From this story you will also learn a mnemonic for chemistry studies.

The pseudonym Nayako Hiisimäki was created by a mother and daughter who wrote the first books together. Now the daughter has grown into adolescence and the mother has written this book alone, but kept her daughter aware of what Nayako wrote and drew. Nayako Hiisimäki is still their common pseudonym.
