Prufrock Press recently sent a note announcing the release of The Ultimate Guide to Summer Opportunities for Teens. Their description focused on college entrance, but I think the book would also be useful for those looking for apprenticeships or mentoring opportunities.
Part of their description reads:
The Ultimate Guide to Summer Opportunities for Teens: 200 Programs That Prepare You for College Success helps teenagers find the coolest, most exciting, and most fulfilling summer programs across the United States. College-planning expert Sandra L. Berger provides students and parents with advice on using summer opportunities to help gain entrance into selective universities, and guidance on researching, choosing, applying for, and making the most out of summer programs.
Students will be able to peruse the directory of more than 200 of the best summer opportunities in the areas of academic enrichment; fine arts; internships and paid positions; leadership and service; math, science, computer science, and technology; and study abroad or international travel, to find the program that fits them best.
You can see purchasing information and sample pages from the book at the publisher’s site here.
