Crossing Game

The fifth book of D.L. Narrol's time travel series has the same steampunk 1912 time-travelers venture again via Dr. Dimitrikov's time machine. They've somehow adopted a misplaced cave lion, an ill-behaved Neanderthal and Olga, the assistant commander of the KGB from their future; The Soveiet Union (1970). Captain Limmerick, tries to have his new companions assisted back to their time periods, but not all goes as planned. Dr. Dimitrikov discovered nuclear fuel when they had previously traveled to the U.S.S.R, in previous book Arctic Quest, but is inept on how to use it. They land in 1992, to discover the KGB has been over-run with corrupt pseudo-capitalism.
The time machine's control panel is, by mistake, tampered with by the hostile Neanderthal, which leads the time travelers to Johannesburg, South Africa (1900), during the Anglo-Boer War. Captain Limmerick evaded this war twelve years prior, in his own time period; but, is compelled to involve himself because of his religious beliefs and his love and admiration for a victimized Zulu woman. Limmerick's distaste for war comes into play, where he changes history forever.
