Illusion - Denise Robertson

Returning home for her sister's wedding, Rachel is looking forward to spending some time with her family... but the weekend doesn't go quite as planned. As soon as she arrives she recognises tension in the air, and with the revelation of her father's adultery, comes even more shocking news...
Shaken to discover that she herself was the result of an affair her father had had years before, Rachel struggles to come to terms with the fact that her much-loved mother isn't a blood relative after all. As cracks begin to appear in her relationship with her long-term boyfriend, as well as with members of her own family, she feels the need to seek out her real mother. But will this desire to get to the whole truth help her, or just lead to further traumas and disappointments?
