It has been nine months since Gordy and his friends, Max and Adilene, stopped Esmerelda from destroying B.R.E.W. and the Vessel. Gordy is starting the eighth grade, where he meets another Dram, Sasha Brexil, whose mother is the new President of B.R.E.W. Gordy has also been practicing new brewing techniques, and has even taken some of his potions to school—something expressly forbidden—but when he starts zoning out during practice, he knows something is wrong.
Strange things are also happening at B.R.E.W., because after Wanda confronts the dark Elixirists, she is unexpectedly fired by Mrs. Brexil. And in Greenland, Mezzarix is offered a chance to escape by an old friend, who is working for the mysterious Ms. Bimini. The woman reveals that she needs Mezzarix to replicate an unusual solution known as “Silt.” Mezzarix agrees on one condition: that Ms. Bimini uses the power of Silt to destroy B.R.E.W. forever.
Both B.R.E.W and the Vessel are in danger, and with the potion world in chaos, it’s up to Gordy, Max, and Adeline to rally the remaining Potion Masters before it’s too late.
Gordy has a new principal this year. And his daughter, Sasha, happens to be a Dram as well, studying to be an Elixirist. But Sasha’s mother takes over as the new president of B.R.E.W. and is particularly ruthless. Meanwhile, Adilene meets a new, mysterious, young friend as well who acts very strange. And a new force helps Mezzarix escape with a new endgame in mind.
The Transparency Tonic is the second installment in the Potion Masters series. This clever fantasy series is just as fun as the previous book – with plenty of adventure and suspense. B.R.E.W. is under attack again, but this time from a mysterious outsider. And Gordy’s new “friend” is extremely annoying and obnoxious. But the other characters were engaging – even the villainous ones. This story builds to a surprising conclusion and a bit open-ended. I look forward to the next in this exciting middle grade series that can’t come soon enough.
