On Order



It has been nine months since Gordy and his friends, Max and Adilene, saved B.R.E.W. (the Board of Ruling Elixirists Worldwide) and the Vessel--the power source for the secret society of potion masters. Now, Gordy is starting the eighth grade, and has been trying new potion brewing techniques, but when he starts zoning out during practice, he knows something is wrong.

Gordy and his friends continue to work on their potions, but when Gordy chooses Max as his lab partner, Adilene starts to wonder if she still has a place with her old friends. She turns to a new friend, Cadence, who might know a way to help Adilene become a potion master on her own.

And in Greenland, Mezzarix has a chance to escape his Forbidden Zone--as long as he agrees to work with the mysterious Ms. Bimini and replicate an unusual solution known as "Silt." It could be just the weapon Mezzarix needs to destroy B.R.E.W. forever.

​With both B.R.E.W and the Vessel in danger, and with the potion world in chaos, it's up to Gordy, Max, and Adilene to rally the remaining Potion Masters before it's too late.

School Library Journal Review

Gr 5-8-Nine months have gone by since Gordy, Max, and Adilene stopped B.R.E.W.'s (Board of Ruling Elixirists Worldwide) destructions at the hands of Esmerelda. Gordy is continuing his education with B.R.E.W. and at school he meets Sasha who is also a dram (an elixirist-in-training). Sasha's mother is the new head of B.R.E.W. and has been making some very strange decisions. To make matters worse, Mezzarix, Gordy's grandfather and one of the most powerful elixirists of all time, has escaped from his exile in Greenland. The mysterious Ms. Bimini asks Mezzarix to brew a special elixir called Silt, which he agrees to do on the condition that she use the power of Silt to destroy B.R.E.W. once and for all. Though Gordy may have the skills to match his grandfather's, but his blackouts may well give Mezzarix the edge that he needs to emerge victorious. This is a wonderful story with an ending that will likely lead readers to beg for more. VERDICT This latest addition to the series picks up where the previous book left off and is filled to the brim with adventure and excitement.-Wayne R.

"Ready to test out the Trapper Keeper?" Max asked Gordy scrunched his nose. "Trapper Keeper? Is that what you're calling it? That's a dumb name." "It's an awesome name!" Max said. Gordy stared down the target, a two-foot tall stuffed elephant, resting upon a cleared-off patch of ground ten yards away beneath a towering dogwood tree. For just a moment, Gordy felt a twinge of regret about what he was about to do. He had won the elephant at a fair several years ago and had kept it in his room ever since. Gordy used to cuddle the floppy thing whenever he freaked out about some odd noise he had heard in the house, and it was one of the only toys that had survived the fire. But he had entered the eighth grade, which meant there was no more room for stuffed animals. Covering the mouth of the flask with his thumb, Gordy shook the liquid aggressively. Lightning bolts cut through the thick goop. Max held his breath, though a high-pitched squeal escaped through his lips as Gordy chucked the bottle. Glass shattered at the elephant's feet, and a dense cloud of smoke mushroomed up from the spot where the potion connected. Gordy shielded his eyes for just a second, but when he looked again, the stuffed elephant had vanished. "That's what I'm talking about!" Max cheered. Gordy approached a fizzling circular patch of ground where the animal once stood. "Well, it won't work exactly the same on a person, but I guess we can say Trapper Keeper is a success." Gordy stepped on the dirt. It felt firm and solid, almost like stone. "The name's warming up to you, isn't it?" Max asked.   Excerpted from The Transparency Tonic by Frank L.
