Spellhacker

From the author of The Disasters, this genre-bending YA fantasy heist story is perfect for fans of Marie Lu and Amie Kaufman. In Kyrkarta, magic-known as maz-was once a freely available natural resource. Then an earthquake released a magical plague, killing thousands and opening the door for a greedy corporation to make maz a commodity that's tightly controlled-and, of course, outrageously expensive.
Which is why Diz and her three best friends run a highly lucrative, highly illegal maz siphoning gig on the side. Their next job is supposed to be their last heist ever. But when their plan turns up a powerful new strain of maz that (literally) blows up in their faces, they're driven to unravel a conspiracy at the very center of the spellplague-and possibly save the world. No pressure.
