" Different to the Regeneration Trilogy in it's setting 'Border Crossing' explores similar themes in what it means to kill someone while drawing on her earlier novels as well. It raises important questions about the nature of good, evil and responsibility, when is a child old enough to understand the consequences of their actions? Although I was intrigued by the plot I struggled to relate to any of the characters, Tom seemed bland in many cases and Danny is an uncertain character, you're not sure whether he was evil or a product of his upbringing and too young to take responsibility. Worth reading for fans but for first timers I'd recommend starting with the Regeneration Trilogy. "
