Why not choose both? Cooperation in Eve has allowed Margarite to have both the Retriever and the Covert Ops skill book before 14:00 Eve Time.
Margarite was on her first mining run after the downtime when she was engaged in chat with a player with 4 alts. This player was just back from 0.0 systems. Where Margarite is, is his home base. This fellow or women had 2 of these alts at 4.0 security status. So the pilots did not seem a threat to Margarite. She chatted with one of the pilots. She told the pilot she was just mining to buy a Retriever. He said, he would give her one for free. Margarite was suspicious. And even when he offered her a contract for a Retriever for 0.00 ISK, she checked it out first with her corp CEO. The CEO said, an Item Exchange should not be a hazard. So Margarite went for it; and now has a free ship. She then bought the skill book for Covert Ops with her ISK. So she made both goals today. And welcome home great hero you will not be forgotten for your gifts to the engineering las Margarite.
