Hi all,
I've just found this offer. The description is as followed:
Amazon First Reads (formerly Kindle First) is a program that offers customers early access to new books across popular genres from Amazon Publishing.
Every month customers can choose one of the six Kindle books selected by our editors for $1.99, or FREE for Prime members. Prime membership fees apply.
Amazon First Reads books can be read on any compatible Kindle device or free Kindle reading app and become part of customers’ permanent libraries.
Joining is free with no purchase obligation. By joining, you receive a monthly e-mail announcing new Amazon First Reads picks. You can unsubscribe from the monthly e-mail at any time by visiting Amazon Delivers E-mail Subscriptions in Your Account.
Please also note:
Amazon First Reads on Amazon.com.au is available to Australia customers only.
Kindle Unlimited subscribers can borrow Amazon First Reads books when they are released. Learn more about Kindle Unlimited.

It seems like you keep the free book for good, not just the month. Unless someone can see otherwise? Great deal.
