I love action / adventure books by authors such as Matthew Reilly, James Rollins, Andy McDermott and Scott Mariani, to name just a few. The first two writers I mentioned have also written books for young adults which are hugely entertaining and so, I'm not against reading books meant for a younger audience. I'm 33 and enjoy feeling younger through the excitement only a book can bring.
Michael Scott has created a highly entertaining world of magic and legend that has the energy and action to appeal to adults as well as younger people. The frenetic pace kicks off immediately and hardly lets up making this a real page turner.
I've already bought book two and look forward to reading it.
It's not just Harry Potter that is capable of casting a spell over readers.
