Multiple Intelligences: New Horizons
by Howard E. Gardner

This book builds in The Theory of Multiple Intelligences by Prof. Gardner and identifies a number of areas in which people demonstrate intelligence, this includes Musical/Rhythmic Intelligence, Mathematical/Logical Intelligence, Bodily/Kinesthetic Intelligence, Visual/Spatial Intelligence, Verbal Intelligence, Interpersonal Intelligence, Intra-personal Intelligence and Naturalistic Intelligence.

This book helps teens to understand their own strengths broadening the measurement of intelligence from the IQ tests we had. It also helps them understand the strengths of their peers and other people they associate with and see their observations in the context of their intelligences. You can read more here.
