Juniper

In the Battle of the Labyrinth, Juniper was Grover's girlfriend. She is a Wood Nymph. Her tree is a Juniper, hence her name.

History
Juniper lives by Zeus' fist at Camp Half-Blood, and stays within her tree most of the time, watching the Camp, and hates dogs, becaue 'she knows about dogs and trees'.

Juniper and Grover start dating sometime between The Titan's Curse and The Battle of the Labyrinth.

In The Battle of the Labyrinth Juniper also tells Percy that she saw Luke entering the Rock where the Labyrinth's opening is in camp, near her tree. She also recalls seeing Quintus doing the same thing. Juniper warns Percy not to trust Quintus.

When they had the battle, her fire gets set on fire. She and Grover try to stop a fire that was damaging her tree, and she joins the battle after that. She also supposedly uses an arrow in battle.

In The Last Olympian, Juniper calls Percy to a meeting with Leneus and Nico, telling him that Grover has disappeared, and she is very worried and heart-sick. Percy soon finds that Grover had been entranced into a deep sleep by Morpheus, and wakes him. Grover is frantic about what Juniper must have gone through while he had been missing, and hurries to the battle. Juniper is very worried about Grover during the battle, but luckily, he survives.

Personality
Juniper is a very sweet Wood Nymph, and is very loving towards Grover. She might be slow for a Wood Nymph, as Grover must have caught up to her, or maybe she just let him catch up.

Appearance
Juniper is small and petite, with wispy hair the color of amber, and a pretty elvish face. She wears a green chiton and sandals, and is said to be a very pretty girl.

Film
In the upcoming film, The Lightning Thief, Juniper will be played by Janine Edwards
