I have read 6 or 7 of them and I do get bored with so many on the same subject and yes I did find out they were better if read in order I have quit lots of books and or authors because they get carried away and write so many books on one subject what really irritates me is to need a book to read pick one up and get started and find it is book 3 or 5 or something or other I try to leave those kinds alone
