The solstice sun strikes the circle of stone...

... and the veil between worlds is changed.

New monsters now walk the earth.

But where did they come from?

It's a new threat for a new season.

But for the first time we're totally stumped. And half of my team is addicted to hunting one of them.

What the heck is that about?

Will I figure it out in time to stop these beasts before they destroy the city?

Midsummer Monsters is the fourth book in the new Druid Detective Agency urban fantasy series. Elijah and Emilie already went through one adventure. Now, ten years after The Druid Legacy, they are facing a new challenge, one that will test their limits. The real threat isn't the otherworldly magic, the magic that once birthed life itself in Eden/Annwn. There was a reason why humanity was cast from the garden groves. When the magic of that place comes home, it won't take long to find out why. The real threat was here all along, hidden in human hearts, now made manifest by the power of creation itself.
