Australian kids' author Andy Griffiths will present his newest comic novel for kids, The 39-Story Treehouse, on Monday, April 20 at 7:30 p.m. Griffiths' books are filled with both zany comedy and many illustrations in the style of Diary of a Wimpy Kid and are popular with kids ages 8-12. Griffiths himself has a reputation as a hilarious presenter, so we expect this event to be particularly fun! Politics & Prose will be selling copies of Griffiths' books, but the program is free and no purchase is required to attend.
