I've found my people!
Darling wonderful people who get DWJ! My family does too. Kids have been fans for years. DD1 went to a WBD event in year 6 as Chrestomanci in a pair of satin pyjamas and a top hat.
Fire and Hemlock possibly my favourite book ever. It is so precious to me I can hardly bear to talk about it. Does that make sense? After my first reading, I had to go away and read The Golden Bough. And read up on True Thomas/ Thomas the Rhymer.
Power of Three marvellous. Who else thinks it's Otmoor?
Time of the Ghost deeply creepy and disturbing.
You must read The Merlin Conspiracy, and its prequel, Deep Secret.
And the Spellcoats quartet.
And, and.... Oh I can hardly write for delight!
Such great writing, superb characterisation, fantastic stories, brilliant humour.
One of the many delights of DWJ's books is the fact that the endings are so seemingly chaotic, but they never in fact fall to bits.
OP- you have a lot of joy to come.
