The Catalogue of the Universe

Blurb

The Catalogue of the Universe is a romance novel for young adults by the New Zealand writer Margaret Mahy, first published by J. M. Dent in 1985.
The book follows the evolving relationship between two teenagers: nerdy intellectual Tycho Potter and high school princess Angela May, who — despite their differences — are best friends. The plot centers around Tycho's observation that things which look as though they "ought" to be simple and symmetric really have a "wobble" to them. This is poignantly demonstrated when Angela's romantic dreams about her father are shattered when she actually meets him.
The book won the Phoenix Award in 2005.
