Spacetime Physics
by Edwin F. Taylor, John Archibald Wheeler · Taylor
Special relativity taught through the invariant spacetime interval rather than Lorentz transformations, using worked paradoxes and problem sets. After it you can reason about simultaneity, time dilation and momentum-energy geometrically instead of algebraically.
