Dedicated to mischief

Have decided that whenever I donate books to charity, I'm gonna put fake dedications in the front of 'em. Craftily, I'll be varying the writing style and type of pen I use, plus the positioning, to keep it real(ish). Here are the first three:

* Charlie, Happy birthday! Hope you enjoy this cheap imitation of a Dan Brown thriller. Uncle Waldo

* Dear Kevin, Good luck at university. Love, Mum and Dad. PS. A few less of these fantasy novels and you might have been studying medicine as we'd always dreamed.

* Mr Martin, Thanks for being a great science teacher. The best part was burning the magnesium. Mikey R.
