Ghost Girl (Ingenuous Serendipity, #4)

The novel, Ghost Girl, picks up where the novel, Seventh Sense,
leaves off. The characters are once again confronted with a series of
adventures as their trail weaves from Nashville to Louisville and then
Pittsburgh. Circumstances take them to a suburb outside Philadelphia
and then move to a dramatic showdown in Washington D. C. Courage,
loyality and trust all come into question as each key character must evaluate
the changing events in their relationships. As with the other three novels
in this series, the ebook version links key songs via the cyber active format.
