Yes that's true. And when looking for something specific, or author's works, Amazon works fine.
It's just when the less detail in your search on Amazon, the more muddled the search gets. I found when looking for something general like 'future Star Trek books' it's not very helpful.
That's where I turn to Memory Alpha. Even the official Star Trek website isn't the best for things like that. And usually Memory Alpha is pretty good about being up to date.
It also keeps me on track, esp. these days when there haven't been books every month. I have to check to make sure I didn't miss something.
I do have "The Captain's Oath" on pre-order from Amazon. When I bought "Available Light" I saw your novel was available at the time for $11 as well. I periodically check the other future releases as well to see if there are any sales (I know they will adjust the price if it goes on sale before it comes, but I noticed with at least one of the Discovery novels it didn't go on sale until a week or so after it was released so I try to wait it out a bit first).
