The Underworld isn’t heaven or hell, it’s kind of where your soul goes before it’s ready to pass on. But the workers here do NOT look kindly on those without their shades (which is physically manifested as a giant hole in, well, your middle).
Penny is also curious as to what became of Reynard’s son, Senator Gaines. After disappearing with Reynard, the senator went right back to work. With his father by his side teaching him how to use his demigod powers…. This can’t be good.
In the search for her shade, Julia has the idea to call on the Free Traders! Remember them? Julia’s coven that got killed by Reynard! They have a map of what they know of the Underworld, but have no clue where they keep the shades…
But Richard (whose body back on Earth is being inhabited by Reynard. Whom Julia was low-key in love with. That guy.) may have a plan to help them out. He creates a diversion so Quentin and Julia can sneak into the Underworld office and find out that the shades are kept at Hades and Persephone's house.
Quentin and Julia made it to Elysium and with the help of one of the many disconnected shades in the house (who use magic to create adorable miracles back on Earth.) Also? Julia discovers something HUGE. Our Lady Underground, who’s invocation actually brought Reynard and death, is REAL!!!
Meet Sylvia. She is Penny’s supervisor at the Neitherlands Library. She’s also kind of a smart ass and decides to help get the head librarian's name for Penny so he can find her book, which hopefully has the way into the Poison Room.
With magic going completely nuts, Eliot decides to “trufie” (truth-roofie) his closest advisors to see if one of them is behind the mayhem. The advisors come clean about some minor infractions but Margo finally let’s lose the truth about the Fairies and is promptly sent to the dungeons.
The whole mess in Fillory is all Margo’s fault, but she is not one to leave her messes for others to clean up for her. She's determined to fix this, and so takes a potion that transports her to the Fairy realm. Fingers crossed she makes it back alive!
