September 30. It starts just as every other day Jax and Lexi have ever lived. Opening your eyes. Stretching while still laying in bed. Yawning. Normal. Until they look into the mirror.

Just as they think they've almost figured it out, their last ounce of normality is changed- swapped- seemingly forever.
