Wolfsbane

Eliza "Eli" Moore has officially become the Mistress of Seers. In order to save reality, she needs to be the Queen of Poisons.

Eli and Dan are back from the past, and everything is wrong. The Moore house is packed with kids, Eli and Tessa aren't friends, people who are supposed to be dead are alive again—and one of those living yet dead souls is none other than Jemima Beauclaire. To make matters worse, Eli can't sense any spirits in this new world, which is especially problematic for a seer.

No doubt about it, Eli and Dan's trip to the past broke the present. Oops.

Fed up after a few days in this new reality, Eli casts a spell put things right—but instead of going home they end up in a second alternate timeline where witches are persecuted and Tessa rules the town from a creepy black mansion on the hill.

Which means they broke reality not once, but twice. Double oops.

No matter which altered reality she's in, the baneful herb wolfsbane—sometimes called Queen of Poisons—pops up everywhere Eli looks. It's growing through cracks in the sidewalk, in fancy pots in her grandmother's solarium, and it's even in her backyard flower bed. Acting on a hunch, she follows the trail. The wolfsbane leads her and Dan to an enemy from Eli's past, but not the one they were expecting. As they encounter setback after setback, Eli wonders how she can repair the timeline when the very fabric of reality is fighting against her.
