Elias and Jobe are 12-year-olds spending a dull summer together. Very, very dull, until they find the book. The book sends them on an adventure that changes everything. Their summer gets even more interesting when they discover there are two girls staying next door, Nenni and Jessi. With a bit of help from the book, the boys build a pool to invite them over, and soon Elias falls in love.
