Lacy

Lacy is a Demigod daughter of Aphrodite. She is Piper's cabinmate and half-sister, and first appears in The Lost Hero.

The Lost Hero
She and Mitchell are the first two members of the cabin who looked after Piper. She and the entire cabin are scared of Drew due to her skills of Charmspeak. When Piper watched Drew toss another camper out of the shower so she could use it, Lacy and Mitchell talk to her while the bathroom door is closed. Lacy offered Piper a collection of clothes to her that the other members of Cabin 10 had donated, while also providing some supplies for her quest. Lacy explained that Aphrodite's Blessing wont prevent her from changing clothes, but then tried to run away before Drew returned. Piper stopped her and tried to at least thank her, but she was very nervous.

Lacy explained how things were run with Drew in charge. If Drew found out she had helped Piper, she could be forced to wear the Shoes of Shame, a hideous pair of white orthopedic nurse's shoes which "don't go with anything." When Mitchell started to explain that Drew controls the cabin with Charmspeak, Drew appeared behind them. Lacy let out a tiny squeak and tried to run away, but Drew put an arm around her to keep her there. When explaining that children of Aphrodite don't have a place on quests, Lacy pointed out that Drew wanted to go on one the night before at the campfire, which earned her an evil glare. Lacy also defended Silena Beauregard, saying that her falling in love and staying in love with Charles Beckendorf didn't cause things to end badly for them, but Drew shot her another look and she melted into the crowd.

As the group of campers started to disperse, Lacy helped Piper pack for the quest and even guarded the door to the bathroom while Piper used it. Before leaving, Piper mouthed Thank you to Lacy and Michell and wondered if Drew had ever thanked them for anything. Lacy returned the appreciation with a full smile.

After returning from her quest, Piper challenged Drew for the position of head counselor. Lacy had a smile on her face and looked back and forth between the two, as if she was watching a tennis match. When Piper says she does have the right to challenge, Mitchell confirms that she can, while Lacy jumped up and down in joy. Once Drew stepped down, Lacy celebrated with the rest of the cabin.

Lacy is scared of Drew, mostly because of Drew's punishments for going against her. However, she likes her half-sister Piper McLean and is friendly towards her, giving Piper supplies for her quest behind Drew's back.
