The Silver Songbird — Nicholas Erik

Kip Keene must traverse time and stop history from being erased in this wild treasure-hunting sci-fi adventure! When Kip Keene's sister Lorelei kills a mutual ally to change history and return home, Keene travels back to 19th century China to stop her from altering the timeline. But upon arrival, Keene's boat is greeted by the substantial fleet of a legendary pirate queen unwilling to share the high seas. Pursued relentlessly across the countryside by multiple enemies, Keene and his partner Samantha Strike realize a terrible truth. If they want to save history - and stop their lives from being completely erased - they might have to do the one thing neither is willing to even consider. They might have to eliminate Lorelei Keene.
