Dude, yes! I am four books in to my series and people get 110k+ word books in less then 48 hours all the time. With my last book I had my first review with in 48 hours of release.
I can only get 1-2 books out a year, which makes it tougher.But some day when I have 10 or 50 books out there and I can finally quit my day job I will go faster... sure.... right...
