The Hidden Magic - The Hidden World Trilogy, #2

Anna Marin has recently discovered an ability to use magic, and she's eager to leave her life as a baker behind to begin training with skilled wizards. Luckily, the perfect opportunity to hone her magic has come up - Jabin is going to the mysterious kingdom of Seamire to track down Noori, the mage who nearly assassinated Prince Grian. However, going with Jabin means defying the orders of both their families and entering dangerous, unknown territories.
Anna's magic won't be the only thing tested as the two track down the Maidens, a secretive group of women wizards who have ties to Noori. Anna and Jabin stumble upon a web of new foes in Seamire, and their hasty pursuit of adventure may have consequences that reach further than they ever could have guessed.
