Lovely ending to a fantastic story-arc. I have loved every second of my journey with Riordan, from 12-year-old Percy in Lightning Thief all the way through to the epic conclusion that I never could have imagined. The lessons on love, on humanity, on boundaries, and on our own limits in changing others are many and they are well-done. The social worker in me LOVED seeing the arc of Meg and her progress with her stepfather.
