Summoning thoughts and whistle

Calling Mrs. O’Leary didn’t always work. Sometimes she was too far away to sense me. Sometimes she was busy doing something else, like digging holes in the Underworld or chewing on a juicy drakon bone. Years ago, Daedalus had left her in my care, but these days she was her own person. She did what she wanted. If I thought about her hard enough, though, she might show up. If that didn’t work, I’d need incentives. I grabbed some treats from Hecuba’s stash. If those failed me, I’d have to go with my last resort. On my keychain, I kept a dog whistle that Leo Valdez had given me.
