The series is a collection of stories from various Sonic the Hedgehog comics, and the last volume (Sonic Select Book 2) was released in 2022.
However, there are a few factors that might make a third book possible:
* Popularity: The Sonic Select series has been well-received by fans. If the books are successful, it increases the likelihood of more volumes.
* New material: There is always new Sonic content being released, including comics. This means there's a constant supply of stories that could potentially be included in a future Select book.
* Demand: If enough fans express interest in a third book, it could influence IDW Publishing (the current publisher of Sonic comics) to consider it.
Ultimately, only time will tell if a Sonic Select Book 3 will be released. The best way to stay informed is to keep an eye out for announcements from IDW or SEGA.
