Enchantment — Pati Nagle

Holly Parker's life changes forever when she visits Enchantment Spring with her older sister Madison.  They hike through the woods, and when they reach the spring, Holly's disappointed.  A concrete coffin full of water?  She expected a pool surrounded by flowers, birds, dancing dragonflies.

But fine. They eat the lunch they packed, and lounge around in the sunshine a while. As they get ready to leave, Holly dabbles her fingers in the water.

And sees a face beneath the surface.

The joy of first love fills her, but Holly's happiness turns to horror when she learns that the government plans to demolish Enchantment Spring.  Her passion for Ohlan - the beautiful water spirit who inhabits the spring - is so strong that she'll gladly risk her life, standing between the spring and the backhoes, to save him.
