Timebound by Rysa Walker is an excellent time travel adventure!
Within a few days of being reunited with her long estranged grandmother, Kate's entire life is turned upside down. Her mother is wiped from existence, her Father is living another, very real life with a different family, Kate has lost everything she cares about. It turns out that Kate is the only person alive who can stop her grandfather from changing both the past and present to shape his needs.
I really enjoy how Rysa Walker is building character relationships, describing their emotions and shaping Kate up to be a formidable player. The technology and time travel science she uses is perfect for the tale and doesn't distract me with a lot of huge "no ways" as other novels have. I am really enjoying her work.
I noticed there is at least one more book in this series and some fan fiction via Kindle Worlds. I may have to check that out!
