The first novel being published by Impetus Press, Jennifer Banash's Hollywoodland, just became available on Amazon. Its official release date is in August, after being pushed back from earlier this summer while press stuff was being prepared.
You can go pre-order it there.
I encourage you to do so.
I've been looking forward to reading it for a long time.
This fall, you'll also be able to pre-order/buy some other Impetus books from Amazon - Jaime Clark's Vernon Downs, Kate Hunter's The Dream Sequence, and, in early winter I think, Fires.
