Ride and Die Again by Lucía Ashta

Inseparable since childhood, Joss and her friends Griffin, Hunt, Layla, and Brady are one of those tightly knit crews that everyone in Ridgemore knows. But celebrating their senior year isn’t turning out quite how they’d pictured . . . especially since reanimating the dead isn’t possible. Right? Right?
For megalomaniac Magnum Chase, anything is possible, and he takes the group of teens to a brand-new “institute” at an undisclosed location, where they’ll learn the perks of their newly discovered immortality. Not only have they been truly reborn; there’s also nothing back home for them to miss, especially not their “parents” and the complex, calculated lies they’ve been telling. It’s heavy, frightening stuff, but the most confusing thing on Joss’s mind is Griffin—and how she feels about him.
It’s not really a convenient time for romance though. It turns out the crew has been under Magnum’s thumb for even longer than they’d suspected. Now, it looks like he’ll be the biggest part of their future as well. But whatever they’re up against, each of them is sure of one thing: they’ll face it together.
