We close this volume with a final commentary from two leaders in the mentoring field. Rhodes and Spencer articulate how the contributions to this volume offer a richer, more complex rendering of relational styles and processes than has been laid out previously in the mentoring literature. They suggest that these efforts should provoke discussion and debate on how relationship styles and mentor-youth interactions influence youth outcomes, particularly as this work continues to draw on knowledge from related fields. The authors conclude with the hope that the work presented here will inform mentoring practices in ways that help youth successfully meet the demands of and flourish in an increasingly complex world.
