Medusa Falling (2023), The Thief (2024), and The Universe Within (2025) form the Cosmic Shores series, published as G.S. Jennsen was also writing the final Shadows & Light trilogy that concludes the Amaranthe saga. The three standalone novels give fan-favorite characters from across the universe their own dedicated stories outside the main series arcs.

The series occupies a different position in the universe than the main sequences — less about civilizational-scale conflict, more about individual character moments in specific settings. For readers who have followed the universe since Starshine, the Cosmic Shores books offer a reward in the form of extended time with characters they know.

The Cosmic Shores trilogy is also collected in the Amaranthe VII omnibus volume alongside the main series collections.

Frequently Asked Questions

How many books are in the Cosmic Shores series?

There are three books in the Cosmic Shores series, published between 2023 and 2025.

What is the first book in the Cosmic Shores series?

The first book in the Cosmic Shores series is Medusa Falling, published in 2023.

Can Cosmic Shores be read without reading the prior Amaranthe series?

The Cosmic Shores novels feature characters who have appeared throughout the Amaranthe universe, and they are best read by readers who know those characters from the Aurora Rhapsody, Asterion Noir, and Riven Worlds series. They are described by Jennsen as self-contained adventures in the sense that each has its own plot, but the emotional resonance depends on familiarity with the characters from their prior appearances. They can also serve as accessible entry points to the universe for readers who want a shorter commitment before tackling the full Aurora Rhapsody sequence.
