Ethan Marcus Makes His Mark (ePub)

"A thoughtful next step for readers of Andrew Clements." —BCCB (about Ethan Marcus Stands Up)

Ethan and Erin go to Tech Camp and try to win a chance to "make" a difference in classrooms everywhere in this hilarious follow-up to Ethan Marcus Stands Up.

Ethan and Erin Marcus may only be eleven months apart age-wise, but they are a million miles apart in every other respect. Ethan's laid back and takes things in stride. Erin's a little more…intense and doesn't really like to go with the flow. So when these two polar opposites are both invited to attend a prestigious invention/maker camp during winter break it seems almost impossible.

Even though Erin and Ethan have reached a kind of truce, Erin thinks that his invitation to the camp was a mistake. And for that reason, Ethan decides to go. He has something to prove to everyone—but mostly to himself—and he's convinced that his desk-evator idea has great potential…if he can do it right.

But the Marcus siblings are going to have to find new partners. This is especially important to Erin whose rival, Romanov, is also attending the camp. Erin's never forgiven him for his comment about "girls" having no place in science. She's determined to beat him.

But then she overhears someone talking about Romanov's project, and decides that she'll never be able to compete with his game-changing invention. So, what now? What if the Marcus siblings combine their ideas, their brains, and their teams, and make something spectacular?

With only one day left, can Erin and Ethan actually create a workable model of their idea, and is it enough to win?
