I suspect, like most readers, if you try a new author and don't like their book for whatever reason, you're unlikely to give them another go. I've plenty of authors I've thought that of - but after reading the third book by a particular author and enjoying it, I then bought books one and two. Not a series so no problem there. I read book two first. It was okay, interesting premise about a boyfriend who has a nervous breakdown, though not as good as book three. Then I read book one, her debut story. Oh dear. I didn't like. Bits of it weren't bad but I realise that had I read this book first, I wouldn't have looked for more by her and I'd have missed book three - which is a keeper.
So, I've revised my reading strategy and unless the books are in a series, I won't go for book one, on the basis that like any job, the writing will likely get better.
I like to think my own writing has improved over the twenty or so books I've written. I know my first paranormal - The Consolation Prize - was a steep learning curve for me and it's the least well written of the Trueblood series. I still grumble about calling it a series because the books all stand alone. Anyway, if any of you have read The Consolation Prize and not wanted to read another of mine - for the first four who comment on this post, I'll send you a copy of Falling for You - FREE!
Assuming you want to give me another try!
