The last magician / Maxwell, Lisa

"In an alternate version of present-day Manhattan, magic is dying, and Esta, a Mageus with a talent for manipulating time, travels back to 1901 to stop the destruction of a book that can possibly restore magic, but in Old New York, Esta must navigate gangs, secret societies, and her feelings for another magician in order to save the future of magic"--OCLC.

Esta, a talented thief with time-traveling capabilities travels back to 1902 to steal a valuable artifact used by an evil magician that caused a rift in modern-day Manhattan which traps magic practitioners. But 1902 is a dangerous time, nothing is as it seems, and Esta faces hard truths about her future which may require a betrayal of those in the past.
