Proofs just came in for the fourth title in my 'Herbie Brennan's Forbidden Truths' series brought out by Faber. The first three books -- 'Atlantis and Other Lost Civilisations', 'Time Travel' and 'Strange Powers of the Human Mind' seem to be doing quite well. (I say 'seemed' because contrary to what many people believe, an author is not kept closely posted about the sales of his/her book. You get the good news or the bad news with your royalty statement, anything from six months to a year after publication... and even then the figures will often reflect only the first few months sales.)
The fourth book, called 'Parallel Worlds', is scheduled for UK publication in January. It's the most speculative one of the series so far -- somebody called it a non-fiction version of 'Faerie Wars' -- but if you like to relax and let your imagination consider some weird possibilities, you'll enjoy it.
In the summer of 2007, Faber are also planning to bring out something very interesting outside of the series I've been writing for them. But I think I'll leave off telling you more about that until nearer the time.
Meanwhile I've started work on the edit of 'Faerie Lord' for Bloomsbury, provisionally scheduled for Autumn next year. Busy days.
