Rowan Liberty, Book One(?)

I believe this is the first Rowan Liberty book, although it does not have any marking indicating that. But the next three books all are clearly labeled Book 2, 3, and 4, so I'm guessing when they did the first one they didn't realize they'd do more, so they didn't mark it. If you know this is incorrect, please let us know. This book includes designs by Kaffe Fassett, Susan Duckworth, Sharon Peake, and Kim Hargreaves, inpired by Liberty's Varuna Wool fabrics.
