Finding Zoe — Cynthia MacGregor

Family-oriented Julia is dismayed when her son finds a “cyber-dad” online to
replace his real dad, absent due to a work project.

As family secrets get uncovered, Julia finally learns what lay behind her
parents' long-ago divorce and also is amazed to discover she has a half-
sister…somewhere. Julia determines to find her, somehow. But her mom won't
help at all.

When the “cyber-dad's” true motives become clear to Julia's son, the boy
panics and runs…right into danger. Can Julia find her son before it's too late?
And will she ever find her half-sister?
