I would like to thank Lucy once again for putting up with all those weekends spent not outside in the lovely summer but inside or for being otherwise bored while I worked on the book—sadly, no Skyrim to entertain you this time as that's still in Chloe's garage but you're gunning for top marks on those Bejeweled type games so, er, best of luck with that!

Thank you, Rohit at Packt for all your kind help, Taabish for your help with the technical editing—your keen eye for detail caught the errors I missed—and all the reviewers and other editors who helped with this book.

Lastly, thank you friends and family for putting up with me.
