The Beaver Theory

Henri Koskinen makes a welcome return in The Beaver Theory, the final book in the trilogy which began with The Rabbit Factor.
Henri has moved in with Laura Helanto and her daughter, but things aren't going well at his adventure park, YouMeFun. Can his beloved mathematics help Henri to save YouMeFun one more time.
The Beaver Theory is the final book in this madcap series. I feel sad that this is the last time I will share Henri's adventures. Henri is like a Finnish Sheldon Cooper (a character in The Big Bang Theory), awkward in social situations, quite often saying the wrong thing, but he can solve problems using mathematical equations. His quirks make Henri a loveable character.
The Beaver Theory is a darkly humourous, sometimes serious, highly entertaining conclusion to this trilogy.
Goodbye Henri. I wish you well in all that you do.
