My dad is my uncle's brother : Who's who in my family?

The family is a thing of many parts - a complicated puzzle made of brothers, sisters, mums, dads, uncles, friends, grandparents. Sooner or later all of us get lost in the maze of kinship, trying to understand who is a great-uncle and a stepfather, who's married to whom, what in-laws are, and why someone who's only just been born can immediately becomes uncle or nephew to someone. The protagonist of this hilarious book, together with his father, ventures to climb his own genealogical tree, happily finding his own place as a part of this big, lively, crowded universe.
